To find out whether the expressions equal 9, plug the values of x and y into each problem. For example, the first expression would be 4 to the power of 2 + 6×1/3, which would simplify to 16+2 which is 18, not 9. The expressions that do equal 9 are B, D, and E.
Answer:
Width = 27
Length = 9
*You might of switched width and length around please check*
Step-by-step explanation:
Width = 3x
Length = x
Perimeter Formula
2(3x+x) = 72
2(4x) = 72
8x = 72
x = 9
Since X was found, plug it in to find the width and length
3(9) = 27
x = 9
