Answer:
12 feet
Step-by-step explanation:
w = width
w+2 = length
w(w+2) = 8
w² + 2w - 8 = 0
(w+4)(w-2) = 0
w = -4 <em>exclude because a length cannot be negative</em>
w = 2
length = 2+2 or 4
P = 2(2)+2(4)
P = 4+8 or 12
=12-5=7
=21-12=9
when u look at they have a diffrence of 2 so the answer will have a diffrence of 2 =11

Answer:
x =4.5
Step-by-step explanation:
this is an isosceles triangle
the legs are equal
4x + 6 = 6x - 3
subtract 6 from both sides
4x +6 - 6 =6x - 3 - 6
4x = 6x - 9
subtract 6x from both sides
4x -6x = 6x - 6x -9
-2x = -9
divide both sides by -2
-2x /-2= -9/-2
x =4.5
