4(-3)^2-5(-13)
-7^2+15
-7^17
Answer:
108
Step-by-step explanation:
The line is leaning to the left, so the slope is negative, eliminate A and D
when x is 3, y is -2, so C is the correct answer
Think about it. The area (the two dimensional version of volume) of a two dimensional shape, like a square, can be 2 feet by two feet. Multiply these together, and you get 4 feet^2, or four feet squared, This is because in order to get the volume, you multiply the base times the height, one side by the other. You make the feet "feet squared" because you are also multiplying the measurements together, too. In three dimensional shapes though, you have three different ways to go. You have the base, the height and the width beyond it. So you multiply them together and get 8 feet^3 or 8 feet cubed (you multiply three measurements together).
Answer:
Dimensions of box
Length is 12 feet
Width is 3 feet
Step-by-step explanation:
Let's assume length of sandbox is L
width of box is W
we are given
A rectangular sandbox has a width that's 1⁄4 of its length
so, we can write as
we know that
area = length*width
so, we get
now, we can plug back W
we can set Area=36
now, we can solve for L
now, we can find W
So, dimensions of box
Length is 12 feet
Width is 3 feet
