Step-by-step explanation:
Multiply first equaton by 2 and add to the other equation
6x+6y=12
<u>5x-6y=15 +</u>
11x+0y=27
11x=27
divide both sides by 11
x=27/11
sub back
3x+3y=6
divide both sides by 3
x+y=2
(27/11)+y=2
2 and 5/11+y=2
minus 2 and 5/11 both sides
y=-5/11
x=27/11
y=-5/11
(27/11,-5/11)
I searched that in my math book dictionary and i found out that adjacent angles are two non-overlapping angles that share a vertex and a side
Width - x
Length - (x+12)
Area - x(x+12)
x(x+12)=220
x²+12x-220=0 -220 =22*(-10), 12=22-10
(x+22)(x-10)=0
x=-22, x=10
For width, we can use the only positive number,
so, the width is 10 feet.
Length is 10+12=22 feet.
