Answer:
90 students.
Step-by-step explanation:
Given 1/4 of the 120 students took woodshop, just take the 3/4 that didn't take it:
![\frac{3}{4}(120)](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D%28120%29)
Find common factors between 4 and 120 to simplify, so 4.
![\frac{3}{1} (30)](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B1%7D%20%2830%29)
Now multiple across to get 90.
Answer:
F(x-h) = x² + 2xh +h² +2
Step-by-step explanation:
F(x) = x² + 2, x∈R
F(x + h) = (x + h )² + 2 = x² + 2xh + h² + 2
