What is the volume of this pyramid? 945 cm³ 1260 cm³ 1890 cm³ 2520 cm³

Hey there! :)

V = 1260 cm³.

Step-by-step explanation:

Volume of a pyramid:

V = 1/3 (bh)

The base is a triangle, so use the formula A = 1/2 (bh).

A = 1/2 (14 × 18)

A = 1/2(252)

A = 126 cm².

Plug this into the volume of a pyramid formula:

V = 1/3 (30 × 126)

V = 1/3 (3780)

V = 1260 cm³. This is the volume of the pyramid shown.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
