I'll give you a study tip. If you actually just break down the problem it's much easier. See how it says 5 tens, it's basically asking you what is 5 times 10
Answer:
72 inches²
Step-by-step explanation:
Let
be equal to the width of the rectangle.
Let
be equal to the length of the rectangle.

Plug in 12 inches as the length

Therefore, the width of the rectangle is 6 inches.

Plug in 12 inches as the length and 6 inches as the width.

Therefore, the area of the rectangle is 72 inches².
I hope this helps!

Step-by-step explanation:
See attachment for graph
Required
a. Determine the slope
b. Find the x intercept and explain what it represents
a. The slope
To calculate the slope, we start by selecting any two corresponding values of x and y from the graph.


Next, we calculate the slope (m)




b. The x intercept
This is the point where

Answer:
x = 10
Step-by-step explanation:
First, we need to isolate all the x's on one side. To do this we need to move the -20 over to the other side making it a +20:
3.5x + 1/2x = 40 + 20 - 2x
Add the x's and the 40 and 20:
4x = 60 - 2x
Move the -2x over to the other side making it a +2x:
4x + 2x = 60
6x = 60
Divide both sides by 6:
x = 10
So x = 10
