3.3x + r = 23.1
-r -r
3.3x = 23.1 - r Divide both sides by 3.3
x = 7 - r
Answer:
Step-by-step explanation:
z= -2
Answer:
-15 + 10x
or
10x - 15
(either one works)
Step-by-step explanation:
You mean you just want me to expand it?
Ok.
Multiply -5 by 3 and -2x.
(-5)(3) = -15
(-5)(-2x) = +10x
Add those together:
-15 + 10x
or
10x - 15
A1 = -7, an = 4(an - 1)
a2 = 4a1 = 4(-7) = -28
a3 = 4a2 = 4(-28) = -112
Therefore, the first six terms are -28, -112, -448, -1792, -7168, -28,672
