Answer:

15(2+5).

Step-by-step explanation:

A way to see distributive property is applying common factor. In this case we have that 30 and 75 are multiples of 15, so we can factor 15 as follows:

15 as a factor of the expression and within parentheses the division of numbers by our common factor.

30+75 = 15(2+5).

15(2+5)= 15*2+15*5 = 30+75.

Step-by-step explanation:

7x + 3x - 18 = 6(x + 3) === Given
10x - 18 = 6(x + 3) === Combine Like Terms === 7x + 3
10x - 18 = 6x + 18 === Distributive Property === 6(x + 3)
10x - 18 - 6x = 18 === Subtraction Property of Equality === -6x both sides
4x - 18 = 18 === Combine Like Terms === 10x - 6x
4x = 18 + 18 === Addition Property of Equality === +18 both sides
4x = 36 === Combine Like terms === 18 + 18
x = 36 / 4 === Division Property of Equality === /4 both sides
x = 9 === combine like terms??

That doesn't use the multiplication property but that's all of the rest of them.

A jewelry box is designed such that its length is twice its width and its depth is 2 inches less than its width the volume of th

Sedaia [141]

Answer:

$Volume = 2x^{3}-4x^{2}$

Step-by-step explanation:

Let x be the width of the jewellery box

Given:

Length of the box is twice its width

Length of the box = $2\times width$

Length of the box = $2\times x= 2x$

depth of the box is equal to 2 inches less than its width.

depth of the box = $width-2$

depth of the box = $x-2$

The volume of the box is 64 inches.

Solution:

We know that the formula of the volume is.

$Volume = length\times width\times depth$

Now we substitute all known value in above.

$Volume = 2x\times x\times (x-2)$

$Volume = 2x^{2}(x-2)$

$Volume = 2x^{3}-4x^{2}$

Therefore, the equation of the volume of the box is.

$Volume = 2x^{3}-4x^{2}$
