5(x+7)+2 = 4(x - 1) + 1

Nadya [2.5K]

Answer:

x = -40

Step-by-step explanation:

First we distribute

5x + 35 + 2 = 4x - 4 + 1

Collect like terms

5x + 37 = 4x - 3

Subtract 37 from both sides

5x = 4x - 40

Subtract 4x from both sides

1x = -40 OR x = -40

Which expression represents the volume of the pyramid? One-fourths2h units3 One-thirds2h units3 s2h units3 3s2h units3

seraphim [82]

Answer:

$V=\dfrac{1}{3}s^2h$

Step-by-step explanation:

The question should be :

A solid right pyramid has a square base with an edge length of s units and a height of h units.

The formula for the volume of the pyramid is given by :

$V=\dfrac{1}{3}\times A\times h$

A is area of base and h is height.

As edge length is s units.

A = (s)²

So,

$V=\dfrac{1}{3}\times s^2\times h\\\\=\dfrac{1}{3}s^2h$

So, the required volume is one-thirds s²h unit³.
