2(3)^2+2
Exponents first.
2*9+2
18+2
20
The answer is 20.
I hope this helps!

To solve this problem you must apply the proccedure shown below:
1. You have the following expressions shown in the problem above:
(<span>8m^2-6/n+3) + (9m^2-4/n+3)
2. As you can see, they have equal denominators, then you have:
(</span><span>8m^2-6+ 9m^2-4)/(n+3)
</span><span>
3. Therefore, when you sum, you have the following result:
(17m</span>²-10)/(n+3)
<span>
The answer is: </span> (17m²-10)/(n+3)<span>
</span>
Answer:
-62
Step-by-step explanation:
y³ – 2y (y – 5) + 13
when y = -3
y³ – 2y (y – 5) + 13
=(-3)³ – 2(-3) [ (-3) – 5] + 13 (by PEDMAS, evaluate parentheses first)
=(-27) + (6) (-8) + 13 (next do multiplication)
=(-27) + (-48) + 13
= -27 - 48 + 13
= -62
