Answer:

V = x³ + 3x² + 3x + 1 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the side ) , then

V = (x + 1)³

= (x + 1)(x + 1)(x + 1) ← expand second pair using FOIL

= (x + 1)(x² + 2x + 1) ← distribute

= x³ + 2x² + x + x² + 2x + 1 ← collect like terms

= x³ + 3x² + 3x + 1

There are 24 people using the gym the ratio of men to women is 2:1 how many men are using the gym?

elixir [45]

I find it easier if you draw out people(not perfectly just make a circle or something) and then circle every 2 people to count for the men. There are 16 men in the gym.

10n^{2} - 12 = -8<br> Please help

torisob [31]

The value for n is $\frac{\sqrt{10} }{5}$

<h3>solving for n</h3>

<u>given data</u>

10n^{2} - 12 = -8

making n the subject of the formula

10n^{2} = -8 + 12

10n^{2} = 4

divide through by 10

n^{2} = 4 / 10

finding the square root of both sides

n = square root ( 4 / 10 )

$n = \sqrt{\frac{4}{10}$

n = 0.632 or $\frac{\sqrt{10} }{5}$
