Hey there
9a+3+2a+10
You have to collect like terms
To simplify you have to add 9a and 2a. Then 3 and 10
9a+2a= 11a
10+3= 13
The answer is 11a+13
hope this helps <span />
7 because 7 x 7 is 49 but if you add 7 and 7 it gets to 14 7 is the answer
so if you do a different number you will be wrong
<h2><em>= 2(x-3) + 2(7x+1) </em></h2><h2><em>since there are 4 sides, 2 which have the same dimensions
</em></h2><h2><em>
</em></h2><h2><em>= 2x - 6 + 14x + 1 </em></h2><h2><em>= 16x - 5</em></h2><h2><em /></h2><h2><em>HOPE IT HELPS (◕‿◕✿) </em></h2><h2><em>SMILE!!

Step-by-step explanation:

Answer:
p = 4
Step-by-step explanation:
The usually recommended procedure for solving a proportion is to "cross multiply", then divide by the coefficient of the variable. (Solve the remaining one-step equation.)
<h3>Cross multiply</h3>
This means multiply both sides of the equation by the product of the denominators:
(15/6)(6p) = (10/p)(6p) . . . . "cross multiply"
15p = 60 . . . . . . simplify
<h3>Second step</h3>
Now, divide by the coefficient of the variable.
15p/15 = 60/15
p = 4
The solution is p = 4.

<em>Additional comment</em>
If the variable is in the <em>numerator</em> of the proportion, using cross multiplication, you will find that you end up multiplying and dividing by the other denominator. To solve it in that case, you only need to multiply by the denominator under the variable.

For example, to solve ...
2/5 = p/10
you only need to multiply by 10. You don't need to multiply by 50, then divide by 5.

Any proportion can be written 4 ways:

This suggests another strategy: invert the whole proportion, then solve it as one with p in the numerator:
6/15 = p/10 ⇒ p = 10(6/15) = 4
