Answer:
4x² + 18
Step-by-step explanation:
note that (c ○ d )(x) = c(d(x))
To evaluate substitute x = d(x) into c(x), that is
c(d(x))
= c(x² + 5)
= 4(x² + 5) - 2
= 4x² + 20 - 2
= 4x² + 18
Answer:50
Step-by-step explanation:
Answer:
56°
Step-by-step explanation:
hii!
to solve this, we need to know that the angles of a triangle all add up to 180 degrees.
we are going to make an x equation here.
2x+3x+40=180
5x+40=180
-40 -40
5x=140
/5 /5
x=28
angle a is 2x, so the answer would be 28*2 which is 56°
