hello!
so the answer that you put there is actually wrong and i'll tell you why and how to do it
so since you are adding the two:
-8x + 9x = x (so you got this part right)
-12 + 4 = -8 (this is where you got it wrong, -12 added 4 goes up in value to -8)
so the final answer is x - 8
i hope this helped and have a nice day!

X^2+x-30 -- find two numbers that add to one and multiply to -30, which would be 6 and -5. so now you have x^2+6x-5x-30. factor out x and 5 to get x(x+6)-5(x+6). so you get (x+6)*(x-5)
Answer:
see explanation
Step-by-step explanation:
Using the rules of radicals/ exponents
× =
⇔
Simplifying each term
7 = 7
x
= x × ×
= x × 3 ×
= 3 ×
= 3
Subtracting the 2 simplified like terms, that is
7 - 3
= 4 ← return to radical form
= 4
3t shirts cost $18
1 shirt will cost 18/3t = 6/t
7t shirts will then cost = (6/t)*7t = 42
7t shirts will cost $42.00
