Answer:
41.1
Step-by-step explanation:
A triangle solver can do this nicely. b ≈ 41.1
__
You can use the law of cosines for the purpose.
b² = a² +c² -2ac·cos(B)
b² = 120² +110² -2(120)(110)·cos(20°) ≈ 1692.1148
b ≈ √1692.1148 ≈ 41.13532
The missing side is b ≈ 41.1 units.

Answer:
C. 62
Step-by-step explanation:
You are adding 8•4=32 with 3•10=30
If the antique's value increases over time, it must be growing (not decaying) in value.
We're told the value increases by 12.12%, which means that if the current value is
, then the value after 1 year is
. Each year, the value increases by the same factor, which means after 2 years, the value is
; after 3 years, the value is
; and so on.
Here
is the starting value of the antique. So the answer is the second choice.
Answer:
x² + 10x - 12
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x(2x - 2) + 6(2x - 2) ← distribute both parenthesis
= 2x² - 2x + 12x - 12 ← collect like terms
= 2x² + 10x - 12
