x + 7x = 56 + 8
Simplifying
x + 7x = 56 + 8
Combine like terms: x + 7x = 8x
8x = 56 + 8
Combine like terms: 56 + 8 = 64
8x = 64
Solving
8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 8
Simplifying
x = 8
Hope this helps, and I hope this is the answer!
Answer:
A = 148 cm^2
Step-by-step explanation:
To calculate the surface area of the cuboid we use the following equation
A = 2 x (lh + lw+ hw) (l: length, w: width, h: height)
A = 2 x (6*5 + 6*4 + 5*4)
A = 2 x (30 + 24 + 20)
A = 2 x 74
A = 148 cm^2
