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
I think the answer is A sorry if wrong
Answer:
22 and 26
Step-by-step explanation:
48-4= 44
44÷2= 22 (first no.)
22+4= 26 (second no.)
Ab+ac=a(b+c) or
ba+ca=a(b+c)
c(m-n)+d(m-n)=(m-n)(c+d)
Zero. That number cannot go into that one
