Abby’s Expression:
Double m, giving 2m. She then takes 20% of the result, which we can write 0.2(2m). Finally she subtracts this from 2m, giving 2m−(0.2)2m
2m − (0.2)2m
Renato’s Expression:
Divide m by 5, giving m ÷ 5 = m/5, and then multiplies the result by 8, giving:
8(m/5)
Answer:
(x-2)(x+4)
Step-by-step explanation:
x² + 2x - 8 = x² + 2x +1 - 9 = x² + x +x+1 - 9 = x(x+1) +(x+1) - 9
=
- ![3^{2}](https://tex.z-dn.net/?f=3%5E%7B2%7D)
= (x+1-3)(x+1+3)
= (x-2)(x+4)
Answer:
is this actually a question
Step-by-step explanation:
Answer:
68.
Step-by-step explanation:
The common difference d = -19 - (-22) = 3
So the 31st term =
a31 = -22 + (31-1)3
= -22 + 90
= 90 - 22
= 68.
