All you need to do is plug in 3 wherever you see an x!
y = 3(3) - 2(3)^2 + 5(3)^3
y = 9 - 2(9) + 5(27)
y = 9 - 18 + 135
y = -9 + 135
y = 126
Hope this helps!

3(3)-2(3)^2+5(3)^3

9-2(9)+5(27)

9-18+135

y=126

Convert 13/8 to a mixed number
Effectus [21]
Given:
13/8

First you have to see how many times 8 can go into the number 13. If you look, 8 can only go into 13 one time, leaving 5 left over.
13-8 = 5
1 with 5 left over
(Rather than writing 8/8, you must simplify to 1 to make it less redundant)

Since there is 5 left over from 8, you would then place it into the numerator place to get:
1 5/8

I hope this helps!
