Answer:
D. 24 Units
Step-by-step explanation:
tracing the points given we get a rectangle
the perimeter of a rectangle = 2a+2b
a=length
b= width
in this case a= 8
b= 4
the perimeter of a rectangle = (2*8)+(2*4)
the perimeter of a rectangle = 16+8
the perimeter of a rectangle = 24
the cheap answer is simply
(x-5)(x²+4x-2)
we can simply multiply the terms on one by the terms of the other and then add like-terms and simplify.
The answer to the question is y=7.
