The answer is N<span>≥ 178. I just had this question and that was right.</span>
Elga's age is 50, and Alvin's age is 56. So, the sum of their ages is 106.
We know that if we had
8/6=2/2 times 4/3=1 times 4/3=4/3
find common factors in top and obttom
factor
48a^4-16a^2-32=(16)(a-1)(a+1)(3a^2+2)
8a^2-8=8(a-1)(a+1)
so we have

(2)(3a^2+2)=6a^2+4
answer is 6a^2+4
Answer:
-38
Step-by-step explanation:
y=2
z=-17
yz-y^2
(2)(-17)-(2)^2
