For A, you take 70% of 421,000 and subtract that from 421,000. You should solve like this: 421,000 - (0.7 x 421,000).
For B, you take 40% of 31.50 and add it to 31.50. (31.50 + (31.50 x 0.4).
This is all I can give for now. Glad to help you!
P = 4(2x^2 + 1)...when x = 3.5
P = 4(2(3.5^2) + 1
P = 4(2(12.25) + 1
P = 4(24.5 + 1)
P = 4(25.5)
P = 102 inches <===
