5
b.
Find the perimeter of the rectangle if x = 10.
x + 2
C.
Write an expression using the variable x to represent
the perimeter of this rectangle.
d.
Evaluate your expression from partc for x = 10, then compare the result to your answer for part b.

3x + 4y -25 =0 represents the amount of change sianna should recieve

b, i believe, but not sure.

c. 6tan80

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
