Answer:

The volume of the given figure is 150 mm³

Step-by-step explanation:

The formula of the volume of the triangular pyramid is V = \frac{1}{3} AH, where

  • A is the area of its base
  • H is its height

The formula of the area of a triangle is A = \frac{1}{2} bh, where

  • b is the length of its base
  • h is the length of its height

In the given figure

∵ The pyramid has a triangular base

∵ The triangle has a base of 12 mm and a height of 7.5 mm

∴ b = 12 mm and h = 7.5 mm

→ By using the 2nd formula above, find the area of the base

∴ A = \frac{1}{2} (12)(7.5)

∴ A = 45 mm²

∵ The height of the pyramid is 10 mm

∴ H = 10 mm

∵ A = 45 mm²

→ Substitute them in the first formula above to find the volume

∴ V = \frac{1}{3} (45)(10)

∴ V = 150 mm³

∴ The volume of the given figure is 150 mm³

What is the solution to (x+6)(x+2)=60
Citrus2011 [14]
Distribute to eliminate the parenthesis

x^2 + 2x + 6x + 12 = 60

Combine like terms

x^2 + 8x + 12 = 60

Subtract 60 from both sides

x^2 + 8x - 48 = 0

Factor the equation

(x+12)(x-4)=0
x+12=0
x+4=0

x= -12 and -4
