Answer:
17. w = 15 18. S = 115°
Step-by-step explanation:
17. 10 · 6 = 4w
<em>combine like terms:</em>
=> 60 = 4w
<em>divided by 4 on both sides:</em>
=> w = 15
18. 180° - S = 65°
<em>subtract 180° on both sides:</em>
=> -S = -115° => S = 115°
Your answer would be three. You'd have to easily just simplify the expression.
Answer:
(x + 4)(x - 8).
Step-by-step explanation:
a²-4a-32
We need 2 numbers whose product is -32 and whose sum is -4.
They are +4 and -8, so the factors are:
(x + 4)(x - 8).
