X^2+26x+c
find the value of c that makes each trinomial a perfect square

c = 169

Step-by-step explanation:

We can use FOIL to determine this after factoring out the equation.

(x+13)(x+13)

F: (x*x)

O: (x*13)

I: (13*x)

L: (13*13)

x^2 + 26x + 169

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
