Answer:

The product of (-4)(7) is -28

Step-by-step explanation:

First you will multiply the number together.

This gets you -28.

The reason it is a negative number is because when you multiply a positive and a negative number together, you get a negative number.

Whereas, if it were two negative numbers, (-4)(-7), or two positive numbers,

(4)(7), the answer would have been positive, 28.

Which expression uses the greatest common factor and the distributive property to rewrite the sum 7 + 75

Lady_Fox [76]

Answer:

$75 + 45$ $= 15(3 + 5)$

Step-by-step explanation:

Given

$75 + 45$ -- Corrected

Required

Use the GCF to write it as a distributive property

First, we find the GCF of 75 and 45

$45 = 3 * 3 * 5$

$75 = 3 * 5 * 5$

The common factor is:

$GCF = 3 * 5$

$GCF = 15$

So, $75 + 45$ becomes

$75 + 45$ $= 15 * 3 + 15 * 5$

Factorize

$75 + 45$ $= 15(3 + 5)$

Hence, the sum has been rewritten as $15(3 + 5)$
