Answer:
Step-by-step explanation:
I did this bfor. You have got to trust me.
Set up the following equations:
110 represents the lengths of the length and width of the triangle, as you'll divide total perimeter of the rectangle, 220, by 2 to find the individual lengths. 20 is the difference between the length and width.
We'll use elimination for this system of equations, as there are opposite coefficients for W in both equations. Combine the two equations:
Divide both sides by 2 to get L by itself:
The length of the rectangle is 65 feet.
Plug this value into the second equation:
Add W to both sides:
Subtract 20 from both sides:
The width of the rectangle is 45 feet.

Answer:
The expression is (64 - x).
Step-by-step explanation:
The statement is:
"the difference of 8 squared and a number"
Let the number be denoted by <em>x</em>.
The value of 8 squared is:
Then the expression for the provided statement is:
(64 - x)
Thus, the expression is (64 - x).
