Answer:
x ≥ 15
Step-by-step explanation:
first we will subtract 10 from both sides
we get x/3 ≥ 5
then we will multiply both sides by 3
and final answer will be x ≥ 15
Step-by-step explanation:
2x^2 + x - 28
= 2x^2 - 8x + 7x - 28
= 2x(x-4) +7(x-4)
= (2x+7)(x-4)
2x+7 = 0 or x-4 = 0
x = -7/4 or x = 4
