Answer:
distributive property
Step-by-step explanation:
(3x + 7) + (2x + 8)
each of the parenthesis has a multiplier of 1 , placed outside the parenthesis.
then multiplying the terms inside the parenthesis by 1 gives
3x + 7 + 2x + 8
When factoring find 2 numbers that when added together equal the middle value and when multiplied equal the last value.
min this problem the middle value is 7 and the last value is 10
5 + 2 = 7 and 5 x 2 = 10
The answer is: (x+2)(x+5)
5a-15+9a=3a+29
We simplify the equation to the form, which is simple to understand
5a-15+9a=3a+29
We move all terms containing a to the left and all other terms to the right.
+5a+9a-3a=+29+15
We simplify left and right side of the equation.
+11a=+44
We divide both sides of the equation by 11 to get a.
a=4
