Hope this helps please lmk if I was right or wrong
5(3x+7)=3(5x+7)
15x+35=15x+21
cancel out the 15x. If you bring over one of the 15x it's going to naturally cancel each other out.
35=21
35 does not equal 21
it would be the equal sign with the slash coming through it
Answer:
x=7
Step-by-step explanation:
Solve.
7x-5x-3=x+4
Calculate like terms.
7x-5x=2x
Rearrange.
2x-3=x+4
Apply inverse addition.
2x-3+3=x+4+3
2x=x+7
Isolate 2x by subtraction.
2x-x=x-x+7
x=7
Answer:
C. (x + 8) (x + 7)
Step-by-step explanation:
<em><u>To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:</u></em>
<em><u /></em>

<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
x(x + 7) 8(x + 7)
(x + 8) (x + 7)
You need to use recursive sequence for this one
