Use the distributive property to express 15+45
Nuetrik [128]
<u><em>Answer:</em></u>
15(1+3)

<u><em>Explanation:</em></u>
<u>The distributive property can be generally expressed as follows:</u>
ab + ac = a(b+c)

<u>The given expression is:</u>
15 + 45

<u>We know that:</u>
15 = 1*15
45 = 3*15

<u>Therefore, the given expression can be written as:</u>
1*15 + 3*15

<u>Taking 15 as a common factor and applying the above rule, we will reach the following expression:</u>
15(1+3)

Hope this helps :)
