Answer:
x =-4
Step-by-step explanation:
4x+9 = -2x-15
Add 2x to each side
4x+2x +9 = -2x+2x-15
6x+9 = -15
Subtract 9 from each side
6x +9-9=-15-9
6x = -24
Divide each side by 6
6x/6 = -24/6
x = -4
Answer: $34.13
explanation:
4 • $9.99 = $39.96 before tax or discount
subtract discount:
$39.96 • 0.2 = $7.992
39.96-7.992 = 31.968
add tax:
31.968 • 1.0675
= $34.13
The answer would be -2 because if you minus x from x^2 then that would be x then plus 2 equals 0 so the answer would be -2. Hope this helped! :)
