The answer is 7. So you would do
2(3)2=12
4(3)=12
12-12=0
0+7
7
There are seven people who each want half an ounce of brocolli. So, you multiply 1/2 by 7, which would be around 3 and 1/2. The actual number, will be 3 and 1/2 though as well.
The y intercept is the initial value, which is graphed on the y axis (or vertical line). In a word problem the y intercept is the original or starting value. In a graph you can find it where the data begins on the vertical axis.
Answer:
width = 5 feet
length = 11 feet
Step-by-step explanation:
Using one variable and setting up two expressions equal to the total area of the rectangle will determine the dimensions of the rectangle.
w = width
l = '4 feet less than three times the width' or 3w - 4
Area = length x width
A = w(3w - 4) = 55
Distribute: 3w² - 4w = 55
Set equation equal to '0': 3w² - 4w - 55 = 0
Multiply 3 x -55 = -165 and find two factors with a product of -165 and sum of -4: -15 and 11.
3w² - 15w + 11w - 55
Group and find the GCF (greatest common factor):
3w(w - 5) + 11(w - 5)
(3w + 11)(w - 5) = 0
3w + 11 = 0 and w - 5 = 0
w = -11/3 not possible to have negative measurement
w = 5 feet
Solve for length: 3(5) - 4 = 11 feet
