To find g(f(-2)) ;

To find g(2) , substitute 2 for x in the given equation

Answer:
x = 1
Step-by-step explanation:
4x - 5/5 = 3
4x - 1 = 3
add 1 to each side of the equation:

x = 1
Ok in one hour the company can spread 3,000 square feet or sqft.
First we need to see which numbers make sense out of 7,500. First we remove the 500 and have 7,000, then we separate 3,000 and for each hour and we are left with 1,000 from here and the 500 we took out before. Now we have a total of 1,500 for the half hour which makes sense because if you add 1,500 for half an hour an 1,500 for another half an hour you get a total of 3,000 which is what we got for the hours above and if you add 3,000 which is for one hour and add 3,000 for the other hour or multiple 3,000 *2 which is the same thing as adding it twice and then add 1,500 for the half hour we get 7,500 total which means 3,000 I'd how much the company can spread in one hour.
If its perimeter, it should be quite easy to find. Just add 12+9+15. Which equals 36. So the perimeter is 36 inches. -Hope it helps!
