Area=LW
L=6+2W
given
A=2808
subsitute
2808=LW
subsitute 6+2W for L
2808=(6+2W)(W)
2808=2W²+6W
divide both sides by 2
1404=W²+3W
minus 1404 from both sides
0=W+3W-1404
farctor, what 2 numbers multiply to get -1404 and add to get 3
-36 and 39
0=(W-36)(W+39)
set each to zero
0=W-36
36=W
0=W+39
-39=W
false, can't have negative dimentions
W=36
L=6+2W
L=6+2(36)
L=6+72
L=78
the length is 78ft
the width is 36ft
0=

Answer:
4
Step-by-step explanation:
The greatest common factor (GCF) is the product of the greatest common factors of the numerical coefficients and the variables involving x and y.
-12(x^4)y - 9x³y² + 3x²y³
-3x²y(4x² + 3xy - y²)
<span>Thus, the answer is letter A. </span>
Answer: -9 1/3 or -9.3333333
Step-by-step explanation: You would just have to divide those two numbers and then add the negative to your answer.
