Answer:

Step-by-step explanation:

The sides add to 63, so:

$11+3x+11+x+2+2x+3=63 \\ \\ 6x+27=63 \\ \\ 6x=36 \\ \\ x=6 \\ \\ \implies AB=2(6)+3=15$

Answer:

Step-by-step explanation:

$f(x)=3x^2-2x+7\\\\f(-2)\to\text{put x = -2 to the equation of a function:}\\\\f(-2)=3(-2)^2-2(-2)+7=3(4)+4+7=12+4+7=23$

Answer:

-cos(2A)

Step-by-step explanation:

We know that (a+b) (a-b) = a^2-b^2

So it means we can simplify to sin^2(A)-cos^2(A) and we know cos^2(A) - sin^2(A) = cos(2A) but we will just multiply by -1 and we get - cos(2A)
