Answer:
48
Step-by-step explanation:
So your equation is: 5y3 - 21 + 6y2 + (25 ÷ 5) and y = 2.
Evaluate for y=2
5(23)−21+6(22)+
25
5
5(23)−21+6(22)+
25
5
=48.
So the answer is 48.

Answer:
here's the answer to your question
Answer: Choice C)
(x-2)(3x) + (x-2)(4)
======================================
How to get this answer? One easy way that might work is to let y = x-2, which will allow us to do a replacement.
We will go from (x-2)(3x+4) to y(3x+4). Now use the distributive property to multiply the y term by each term inside
y(3x+4) = y*3x + y*4 = (y)*(3x) + (y)*(4)
The last step is to re-introduce y = x-2 back in. So replace y with x-2 like so
(y)*(3x) + (y)*(4) = (x-2)*(3x) + (x-2)(4)
