Answer:
1060 feet
Step-by-step explanation:
The computation of the perimeter of the rectangle is as follows;
As we know that
Perimeter of the rectangle = 2 × ( length + width)
where
Length of x = 5
And, the width be 5x^3 - 4x^2
= 5(5)^3 - 4(5)^2
= 625 - 100
= 525
Now the perimter is
= 2 × (5 + 525)
= 1060 feet
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4
<span>x^2 + 12x = 11
</span><span>x^2 + 12x + 36 = 11 + 36
</span>(x + 6)^2 = 47
answer
the number should be added to both sides <span>of the equation to complete the square = 36</span>
