Answer: C
Step-by-step explanation:
Supplementary angles add up to 180
x + 83 = 180
x= 97
A(42) = 3(42) - 8
The 42nd term is 118.
Answer:
AB
Step-by-step explanation:
Using FOIL (first outer inner last) u can determine that the final term will be produced by multiplying the last terms in each bracket. These are A and B, so the final term of the resulting trinomial is AB.
You can check this by fully expanding (x + A)(x + B):
the terms B and A are usually numbers, so Bx and Ax tend to get added together to form a middle term. hope this helps!
Answer:
3/4
Step-by-step explanation:
Dividing by a fraction is the same as multiplying by its reciprocal.
Answer:
a) x=5
b) x=6
Step-by-step explanation:
a)
3x+7=180-(10x-22)
3x+7=202-10x
13x=195
x=5
b)
11x-3=4x+39
7x=42
x=6
I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.
