Answer:
the length and width be 13.33 feet and 34.67 feet respectively
Step-by-step explanation:
The computation is shown below:
Let us assume the width be x
So, the length be 2x + 8
As we know that
The perimeter of the rectangle = 2(length + width)
96 = 2(2x + 8 + x)
96 = 4x + 16 + 2x
96 - 16 = 6x
80 = 6x
x = 80 ÷ 6
= 13.33 feet
So, the length would be
= 2 × 13.33 + 8
= 34.67 feet
Hence, the length and width be 13.33 feet and 34.67 feet respectively

Answer:
.75
Step-by-step explanation:
Point slope form
y - -6 = (-1/2)(x - -4)
y + 6 = (-1/2)x - 2
y = (-1/2)x - 8
Answer: y = (-1/2)x - 8
Check. Clearly slope is -1/2, good. (-1/2)(-4)-8=2-8=-6 good
