Answer:
L = 16 W=3
Step-by-step explanation:
Let width = x
Length = 4x +4
Area = 48
Area = L times w
48= (4x+4)(x)
48 = 4x^2 +4x
0 = 4x^2 +4x -48
0= 4(x^2 +x-12)
0 = (x+4)(x-3)
x = -4
x=3
Ignore the -4 because it's unrealistic to have negative length width or area
Hence, only solution is 3
Width = 3
Length = 4x + 4 = 4(3) + 4 = 12+4 = 16

Answer:
<h2>652 ft²</h2>
Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
Answer:
B. 90
Step-by-step explanation:
angle of rotation = 360/4= 90
Answer:
y=28
Step-by-step explanation:
6x-y=2
-y=2-6x
y=6x-2
4x-(6x-2)=-8
4x-6x+2=-8
-2x=-10
x=5
y=6*5-2=30-2=28
y=28
