Answer:

x=17

Step-by-step explanation:

2(x-7)=(x+3) divide both sides by two

2x-14 =(x+3) distribute

2x-14-x-3=0 substract x+3

x-17=0 combine like terms

x=17 add 17 to both sides

How is the distributive property used to expand expressions? provide an example

Pepsi [2]

Yes the distributive property is used to expand expressions, but it is also used to make it simpler.
For an example

3(x+4) + 3(y-8)
This is the same thing as
3x + 12 + 3y -8

What is the difference of the volumes of the two oblique pyramids, both of which have square bases? Round the volumes to the nea

ad-work [718]

Answer:

Step-by-step explanation:

See attachment for the figure

Volume of pyramid can be defined as

V = 1/3 x area of the base x height.

-> Pyramid A:

Volume of Pyramid can be determined by:

V = 1/3 x (2.6cm)² x (2cm) = 4.5067 cm³

Pyramid B:

Volume of Pyramid can be determined by:

V = 1/3 x (2cm)² x (2.5cm) = 3.3333 cm³

Difference b/w two oblique pyramids: 4.5067 cm³ - 3.333 cm³ = 1.17 cm³

By Rounding the volumes to the nearest tenth of a centimeter

1.17cm³ ≈ 1.2cm³

Therefore, the difference of the volumes of the two oblique pyramids is 1.2cm³
