Answer:
Question 1: -2xy + 7x
Question 2: 8t - 4v and -4v + 8t
Question 3: -e + 10k and 10k -e
Question 4: x = -3
The answer is c=250 feet because the circumference is twice the radio us I’m pretty sure.
In order to answer this, we need an image to be able to see what they look like.
Tom--------------
>10 sq ft per minute
Tim-------------------
>3.5*10=35 sq ft per minute
Both painters (10+35)=45
sq ft per minute
let's assume a cubic unit crate----------> V1=1*1*1=1 feet3
<span>the total surface of the cube is S1=6*(1*1)=6 </span>sq
ft
if the volume of the cube increases twice
V2=2 feet3 ------------------- > 2=x*x*x------------- >x=2^(1/3)
And the S2=6*(2^(1/3)*<span> 2</span>^(1/3)=9.5244 sq ft
V2/V1=9.5244/6=1.5874
Therefore
If Tim and Tom-----------------------
> take 1 day----------- > to paint a crate V1
For the crate V2------------- > take 1.5874 days
assuming an 8-hour work day
0.5874*8=4.70 hr-------------- > 4 h 42 min
The answer is 1 day 4h 42 min
