Answer:
no solution
Step-by-step explanation:
7m-(5m-12)= 8+2m+4
2m+12= 2m+4
Perimeter of a rectangle is given by (2 × Length(l)) + (2 × Width(w)) = 2l + 2w
l= 11 feet
2(11) + 2w = 46
2w = 46 - 22 = 24
w = 24/2 = 12 feet
Width = 12 feet.
b
(x+12)^2=1
or
(x+12)= +or - 1
when
x+12=1
x=1-12 =-11
x+12=-1
x=-1-12 =-13
then
x=-11 and x= -13
true
