I think it's 144
multiply 12 by 4 because there are 4 walls then multiply 3 by the product of 12×4 and that should be your awnser
All you have to do is subtract the two degrees to get your answer
Answer:
1. 550 miles
2. $103
Step-by-step explanation:
y = total rental cost
m = initial fee
x = cost per mile
n = number of miles
Plan 1: y = m + xn = 59 + 0.08n
Plan 2: y = m +xn = 48 + 0.10n
Q1. if total cost is the same : 59 + 0.08n = 48 + 0.10n >>> 0.02n = 11 >>> n = 550
Q2. y = m + xn = 59 + 0.08n = 59 + 0.08(550) = 103
Answer:10,374
Step-by-step explanation:
Answer: -27 = (x - 8)²
<u>Step-by-step explanation:</u>
-5x² - 456 = -80x - 1
-455 = 5x² - 80x <em>added 5x² and 1 to both sides</em>
-91 = x² - 16x <em>divided both sides by 5</em>
↓

-91 <u>+ 64</u> = x² - 16x <u>+ (-8)²</u> <em>added (-8)² = 64 to both sides</em>
-27 = (x - 8)²
