You can work this out by rearranging the equation and isolating the x.
4x + 12 = 36
4x = 36 - 12 (I moved the +12 to the other side, which means it becomes -12)
4x = 24 (36 - 12 = 24)
x = 24 / 4 (You need to isolate the x, and because it was being multiplied by 4, I divided both sides by 4 to leave me with just x)
x = 6 (24 divided by 4 is 6).
Answer:
1,536 square centimeters
Step-by-step explanation:
The formula for the Lateral surface area of the pyramid =
1/2 × perimeter of the square base × slant height
Square base = 32cm
Slant height = 24cm
Perimeter of the square base = (4 × length of the square base side)
4 × 32cm = 128cm
Lateral Surface Area = 1/2 × 128cm × 24cm
= 1,536 square centimeters
