Answer:
x ≤ 3
Step-by-step explanation:
3x-2 ≤ 2x+1
Subtract 2x from each side
3x-2x-2 ≤ 2x-2x+1
x-2 ≤ 1
Add 2 to each side
x-2+2 ≤ 1+2
3x -2 ≤ 2x +1
3x ≤ 2x +3
so its {x|x∈ℝ, x ≤ 3}
18h +4
The perimeter of a rectangle is given by
P = 2(l+w) where l is the length and w is the width
=2( 7h+8 + 2h-6)
Combine like terms
= 2( 9h+2)
Distribute
= 18h +4
You need to study to do good on those exams bud.
