Step-by-step explanation:
(3k - 2)(5k + 4)= 15 k^2 +12k - 10 k - 8 = 15 k^2 + 2k -8
Answer:
3 min.
5 balloons.
Step-by-step explanation:
How many minutes does it take to make one balloon sculpture?
t = (Total time) / (Total identical balloon sculptures) = 96 / 32 = 3 min.
How many balloons are used in one sculpture?
n = (Total balloons) / (Total identical balloon sculptures) = 160 / 32 = 5 balloons.

= 6x + 2 + x - 4 + 3x + 1
= 10x - 1
