Answer:
{2, 3, 4, 6, 8, 9, 12, 18}
Step-by-step explanation:
If A= {x: xis a factor of 72}
A = {2, 3, 4, 6, 8, 9, 12, 18, 36, 72}
If B= {x: 2x+3<2x-3).
-2x+3 <2x-3
-2x - 2x < -3-3
-4x < -6
x > 3/2
If
C= {x:x<20}
C = {-∞, 19}
The intersection of the sets AnBnc = {2, 3, 4, 6, 8, 9, 12, 18}
Note that intersection means all the elements common to the three sets

When you have something multiplied by more than one term in parentheses, you multiply that something (in this case 6) by both terms (x and y).
6x+6y+x+y. Add like-terms. 7x+7y
Expression: 80+15x=y
(x means months)
so at the end of the year jason will have $260
Answer:
7(x-2)(x+2)
Step-by-step explanation:
7x^2 -28
Factor out a 7
7(x^2 -4)
The terms inside the parentheses is the difference of squares, so it is factorable (a^2-b^2) = (a-b)(a+b)
7(x-2)(x+2)
I just did the first one but I don't know is it correct
