Answer:
16
Step-by-step explanation:
We can count the number of sides of the shape, with every gridline being 1 unit.
The perimeter is the outline of the shape.
There are 16.
16*1 unit = 16

The side length is 12 - -3 = 15 so the area is 15 squared = 225.
Answer:
E. -8/3
F. 8/3
Step-by-step explanation:
9x^2-64=0
Add 64 to each side
9x^2-64+64 = 0+64
9x^2 =64
Divide each side by 9
9x^2/9 = 64/9
x^2 = 64/9
Take the square root of each side
sqrt(x^2) = ±sqrt(64/9)
We know that sqrt(a/b) = sqrt(a)/sqrt(b)
x = ±sqrt(64)/sqrt(9)
x = ± 8/3
