<em><u>The equivalent expressions are:</u></em>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the equivalent expressions
By distributive property,
a(b + c) = ab + ac
Therefore,

Thus equivalent expressions are found
The measurement around the crater is the circumference. We need to find the radius so we can find the area fo the crater.

Plug in values
79.5=2*(3.14)r
Multiply 2 and 3.14
79.5 = 6.28r
Divide both sides by 6.28
r approximately 12.66 miles
Area of a circle

Plug in values
A=(3.14)*12.66^2
Area = approximately
503.27 Sq Miles
Answer:
81 million
Step-by-step explanation:
In one year there is 365 days, if you divide 365/4.5 the answer is 81.1. And every 4.5 days add 1 million people, then you multiply
81.1*1 000 000 = 81 100 000
approaching to the nearest million, 81 million of babies are added each year.
Answer:
x=-1/2
Step-by-step explanation:
-5(x-3+7x=35)=-5(x-3+7 <em>x </em>35=x)
(-5)x+(-5)(-3)+(-5) <em>x</em> 7x=35
-5x+5x<em>x </em>3-5 <em>x </em>7x=35
-40x+15=35
