Solve step by step 3(2x-4)=8

olganol [36]

Answer:

x = 3.33... or 10/3

Step-by-step explanation:

3(2x - 4) = 8

distribute the 3 into the parentheses

3 • 2x = 6x

3 • -4 = -12

6x - 12 = 8

add 12 to both sides

6x = 20

divide both sides by 6

x = 3.33... or 10/3

Find the volume of the pyramid. round to the nearest hundredth

hichkok12 [17]

Answer:

A. 17.35 mm³

Step-by-step explanation:

<u>Volume of a Pyramid</u>

$V = \frac{1}{3}Bh$

V ... volume

B ... area of base

h ... height

The base of this pyramid is a square. Area of a square is side times side.

$B = 3.5 \times 3.5$

Let's substitute in the formula.

$V = \frac{1}{3}Bh\\\\V = \frac{1}{3}(3.5\times 3.5)(4.25)\\\\V = \frac{1}{3}(12.25)(4.25)\\\\V \approx 17.35417 \text{ mm}^3$

Now let's round to the nearest hundredth.

V = 17.35 mm³
