Which expression results from using the distributive property 2(5 + r)
Vinvika [58]
Using the distributive property we know we distribute by multiplying the outside values to those inside of the parentheses

outside values: 2

inside values: 5 and r

now multiply out inside values by the outside values

2x5 = 10

2xr = 2r

now plug these values back in for the inside values and take away the outside value and the parentheses

so 2(5+r) using the distribution property is 10+2r

Find the volume of a pyramid with a square base, where the perimeter of the
lianna [129]

Answer:

42.7\,\,cubic\,\, meters

Step-by-step explanation:

Given: Perimeter of base of a pyramid = 12.8 m

Height of the pyramid = 12.5 m

To find: volume of a pyramid

Solution:

Perimeter of base of a pyramid = 12.8 m

As base of the pyramid is a square,

12.8 = 4(side\,\,of\,\,a\,\,square)

side of a square = \frac{12.8}{4}=3.2\,\,m

Area of a square (A) = (side\,\,of\,\,a\,\,square)^2=(3.2)^2=10.24\,\,m^2

Height of the pyramid (h) = 12.5 m

Volume of the pyramid = \frac{Ah}{3}=\frac{1}{3}(10.24)(12.5)=42.7\,\,cubic \,\,meters
