Answer:
=14s4−7s2+15
Step-by-step explanation:
Steps:
1: Distribute the Negative Sign
=12s4−6s2+4s+6s4−4s+27+−1(4s4+s2+12)
=12s4+−6s2+4s+6s4+−4s+27+−1(4s4)+−1s2+(−1)(12)
=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12
2: Combine Like Terms
=12s4+−6s2+4s+6s4+−4s+27+−4s4+−s2+−12
=(12s4+6s4+−4s4)+(−6s2+−s2)+(4s+−4s)+(27+−12)
=14s4+−7s2+15
Answer: =14s4−7s2+15

6 gift boxes are 12.36 inches high
32 gift box are x inches high
This is a proportion question. A proportion is made of 2 equal ratios. If you know 3 parts of the proportion, you can solve for the 4th,
6/32 = 12.36/x Cross multiply
6x = 12.36 * 32 Combine the right.
6x = 395.52 Divide by 6
6x/6 = 395.52/6
x = 65.92
Answer: 65.92
Note
Using a proportion saves you the trouble of finding 1 box and multiplying whatever number you get by 32
