Answer:
Step-by-step explanation:
6x-1=2x+5+4x-6
separate the variables in one side, numbers on the other side
6x-2x-4x=1+5-6

Answer:
m=217 miles/31 days
Step-by-step explanation:
Carl has to run 217 miles in 31 days; to find the number of miles
he needs to run per day, he should divide the number of miles he has to run (217 miles ) by the number to days he will run ( 31 days):


Carl has to run 7 miles per day. We can confirm this result by multiplying this by 31 days, and we should get 217 miles:

Answer: 3x⁵ - 2x⁴ - x² + x - 21
<u>Step-by-step explanation:</u>
f(x) = 3x⁵ + 6x² - 5
<u> - g(x)</u> = <u> -2x⁴ - 7x² + x - 16</u>
(f - g)(x) = 3x⁵ - 2x⁴ - x² + x - 21
15/12= 1.25
6.4x1.25=8
x = 8
Left and right side: 6.4*7=44.8
44.8+44.8=89.6
front (where the zipper is) and back: half of 5*8=20
20+20=40
40+89.6=129.6
the area of the bottom is 7*8=56
the total area is 129.6+56=185.6
I am not sure what lateral area includes. To me, the answer should be 129.6, but 129.6 is not a choice.
I'd suggest 185.6, the total surface area.
