If f(x) = -x-11 ; find the following.
4f(-2) + 5f(1)

I believe -102 is the answer you are looking for.

Step-by-step explanation:

4(-2 - 11) + 5(1 - 11)

4(-13) + 5(-10)

-52 + (-50)

-102

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

d is ur answer hopes this i dont really know how to explain it to u.
