Answer:

Step-by-step explanation:
i have no idea if its right...
The answer is:
5f^2+11f-2
Explanation: All you would have to do is combine the like terms. For example; -3f^2 amd 8f^2 are both like terms because they both have the same variables and powers. Ignore the variables and powers for a second. Look at the coefficients. -3 and 8 are to be added since the 8 is a positive. Once you add them, the result will be 11f^2. You need to remember to add back the variable and power. It just seems easier that way. There is also another like term in the polynomial. 4f and 7f. You add those to get 11f. The last like term in the polynomial is -3 and 1. You add -3 to 1 and you get -2.
I hope this explanation made sense to you as I tried my best to explain it! :)
Let the width be x
if width =x
length =3x
area=10092
area=length x width
10092=3x x x
10092=3x²
10092/3=x²
3364=x²
√3364=√x²
x=58
width=58m
length=58x3
=174m
perimeter =2(L+W)
=2(174+58)
=2 x 232
=464m
M = r + 3
a = 2m......a = 2(r + 3).....a = 2r + 6
m + r + a = 57
(r + 3) + r + (2r + 6) = 57
4r + 9 = 57
4r = 57 - 9
4r = 48
r = 48/4
r = 12.......rahfat is 12
a = 2r + 6
a = 2(12) + 6
a = 24 + 6
a = 30.......aurello is 30
m = r + 3
m = 12 + 3
m = 15 <=== mel is 15
