Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

the rectangle below has an area of x^2-6x-7, square meters and a width of x-7 meters.What expression represents the length of the rectangle?
Answer:
Length = (x^2-6x-7)m²/ (x-7)m
Step-by-step explanation:
let L =length
let W= width
let A = area of the rectangle.
if A = L × W
making L the subject, divide both side by W
A/W= L×W/W
therefore, L =A/W
L= (x²-6x-7)m²/(x-7)m

Explain the cosine rule and sine rule while also saying how to use it and provide examples (keep it in simple terms)
Answer:
Sure, I'll explain the cosine rule and sine rule in simple terms:
The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.
Here's an example of how to use the cosine
Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.
Using the cosine rule:
a^2 = b^2 + c^2 - 2bc * cosA
where A is the angle opposite side a, we can plug in our values and solve for a:
a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)
a^2 = 64 + 36 - 96 * 0.707
a^2 = 10.56
a = sqrt(10.56)
a = 3.25 (rounded to two decimal places)
Therefore, the length of side a is approximately 3.25 units.

Wayne thinks of a number, multiplies it by three, and adds 10. His answer is 11 more than the number he originally thought of. If x is his original number, write an equation in terms of x and solve it to find x.
Step by step is possible pls
Answer:
x = 1/2 or 0.5 in decimal
Step-by-step explanation:
Let the number Wayne thought of be x
He multiplies it by 3 ==> 3x
Then adds 10 ==> 3x + 10
11 more than the original number = x + 11
Setting both sides equal to each other we get
3x + 10 = x + 11
Move x to the left side from the right side; sign of x changes
3x - x + 10 = 11
==> 2x + 10 = 11
Move 10 from left to right side(sign changes for 10)
2x = 11 - 10
2x = 1
x = 1/2 or 0.5 in decimal
Verify
3x + 10 = 3(1/2) + 10 = 3/2 + 10
3/2 = 1 1/2 so 3/2 + 10 = 1 1/2 + 10 = 11 1/2
x + 11 = 1/2 + 11 = 11 1/2
So left side = right side
Answer:
Part 1: Substitution method
Part2: Wayne has 57 coins
Part 3: Winston has 49 coins
The first step is solve find the equations for the information given.
Let x be the number of coins that Wayne has and y be the number of coins Winstone has.
Winston has 8 fewer coins than Wayne has. y = x − 8
If you add 4 times the number of coins Wayne has and 3 times the number of coins Winston has, the sum is 375. 4x + 3y = 375
Part 1
y = x − 8
4x + 3y = 375
This equations can be solved simultaneously by use of substitution method.
Part 1 and part 2
y = x − 8 (i)
4x + 3y = 375 (ii)
Substitute the value of y with (x - 8) in equation (ii).
4x + 3(x - 8) = 375
4x + 3x - 24 = 375
7x = 375 + 24
7x = 399
Divide by 7 both sides of the equation
x = 399/7
= 57
And y = x - 8
y = 57- 8
y = 49
Wayne has 57 coins
Winstone has 49 coins

identify a rational number with a square root between 0.7 and 0.8.
ASAP PLZZZZZZ
PLZ PROVIDE SHORT EXPLANATION!!!!!!
Answer:
0.73
Step-by-step explanation:
A rational number is any kind of decimal, fraction, or negative number, or whole number. This is a decimal, so you can go from in-between 0.71-0.79, any of those numbers will work.
A rational number is a number that is expressed as the ratio of two integers,3/4 is the rational number between 0.7 and 0.8.
What are Rational Numbers?'A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero
The given two rational numbers are 7/10 and 8/10 because
0.7 = 7/10 = 70/100 and 0.8 = 8/10 = 80/100
So any proper fraction between 70/100 and 80/100
Let us consider 75/100 = 3/4
Squaring 3/4 we get 3/4×3/4 = 9/16
So 0.7 <sqrt(9/16) < 0.8
0.7 <0.75 < 0.8
Hence 3/4 is the rational number between 0.7 and 0.8.

A 168-yard-long field is divided into 12 parts of equal length. Mr. Gump paints a 6-yard-long strip in each part. How long is the unpainted strip in each part of the field?
Answer:8 Yards
Step-by-step explanation:
168/12=14 yards long.
14-6=8
The unpainted strip is 8 yards long.
Answer:
The unpainted strip in each part of the field is 8-yards-long
Step-by-step explanation:
168 divided into 12 equal parts would be: 168/12=14
and a 6-yard-long strip in each of those 14 parts would leave 8 yards unpainted in each of the 14 strips: 14-6=8

Answer: The speed of the car is 45.3 miles per hour.
Step-by-Step Explanation: Let 'x' be the speed of the car.
60 × 2/3 = 120/3 = 40
30 × 1/5 = 151/5
151/5 /40 = x / 60
151 / 200 = x / 60
=> x = (151×60) / 200
=> x = 45.3
Answer:
The car was traveling at an average speed of 45.3 miles per hour.
Step-by-step explanation:
We need to figure out how many minutes are in 2/3 of a hour. If we divide 60 minutes by 3 we get 20 minutes, so 2/3 of 60 minutes is (20 minutes x 2) 40 minutes.
We now know that the car traveled 30.2 miles in 40 minutes. We want to know if it traveled for 60 minutes, what would the average speed be. The ratio will be the same, so we want to solve for x (miles):
30.2/40=x/60
We then cross multiply:
30.2x60=40(x)
1,812=40(x)
Divide each side by 40
1,812/40 = x
x=45.3
here are some numbers 2 9 14 36 40 what number is a multiple of 12 which number is a prime number which number is a factor of 64
Answer: 36 is a multiple of 12
2 is a prime number.
2 is a factor of 64
Step-by-step explanation:
12 × 3 =36, so 12 is one of the factors.
2 is the only even prime number. All other even numbers are multiples of 2.
9 is not a prime number. 3 × 3 = 9
2 is a factor of 64. 2 × 32 = 64 None of the other numbers given can divide evenly into 64, so they are not factors of 64.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
