Option A

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

<em><u>Product of powers property:</u></em>
The product of powers property tells us that when you multiply powers with the same base you just have to add the exponents
Which is represented as,

<em><u>Therefore, the given expression becomes,</u></em>

Now add the exponents, we get

Simplify the above expression

Simplify the exponent of y, we get

Thus Option A is correct
Answer:
25, 36, 49
Step-by-step explanation:
I just listed them down since there aren't many.
1×1=2 (Smaller than 20)
2×2=4 (Smaller than 20)
3×3=9 (Smaller than 20)
4×4=16 (Smaller than 20)
5×5=25
6×6=36
7×7=49
8×8=64 (Bigger than 50)
12.56 cubic inches
Step-by-step explanation:
Volume of a cone= π r² h/3
3.14*2*2*3/3
3.14*4*3/3
12.56*3/3
=12.56 cubic inches
Ok so idk if I'm right but y= -2x+21
