i think the answer is 8
bc the small one is 4 and the big one is 6
and the other one is 6 so it must be 8
You need to isolate the "x" in both inequalities
5x + 7 ≤ -3 Subtract 7 on both sides
5x ≤ -10 Divide 5 on both sides
x ≤ -2
3x - 4 ≥ 11 Add 4 on both sides
3x ≥ 15 Divide 3 on both sides
x ≥ 5
This is your simplified inequalities:
5x + 7 ≤ -3 or 3x - 4 ≥ 11 ---------> x ≤ -2 or x ≥ 5 Your answer is A
Surface area = πr(r + l)
500π = 15π(15 + l)
100 = 3(15 + l)
100=45+3l
100-45=3l
55=3l
l=55/3
l=18.3ft to one decimal place
