4x + 8 - 36 first subtract 36 from 8 to get the simplified equation 4x + (-28), or 4x - 28. As you cannot combine these terms, this is as far as you can go. Hope this helps! :)
12+6n=30
6n=18
n=3
So the number would be three

Answer:
A=61.5cm^2
Step-by-step explanation:
Area= 5*1/2(lh)
A=5*1/2(6*4.1)
A=5*1/2*24.6
A=5*12.3
A=61.5cm^2
Answer:
Width of the box = 2 inches
Step-by-step explanation:
Volume of a box = length × width × height
Volume of the box = 240 cubic inches
Length of the box = (x + 8) inches
Width of the box = x inches
Height of the box = 12 inches
Volume of a box = length × width × height
240 = (x + 8) * x * 12
240 = (x² + 8x) * 12
240 = 12x² + 96x
12x² + 96x - 240 = 0
x² + 8x - 20 = 0
Solve quadratic equation using factorization method
x² + 10x - 2x - 20 = 0
x(x + 10) -2(x + 10) = 0
(x + 10) (x - 2) = 0
x + 10 = 0 OR x - 2 = 0
x = -10 OR x = 2
Width of the box can not be a negative value
Therefore,
Width of the box = 2 inches
