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=
If signs are different you subtract. So 2.5- -1.25 equals 1.25 and keep the sign of the biggest number
Answer:
yes, by AAA~
Step-by-step explanation:
to find the missing angles subtract 180 - 125 - 27 = 28
then we have all of the angles and we can see they are congruent
Ur answer is 2% because u minus it and u find the percentage
