I got 0.3125 (i don’t know if that’s correct, because the question was hard for me to understand)
<em>1. x = - 7/3 = - 2 1/3</em>
<em>2. x = -2</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3x + 12 = - 6x - 9</em>
<em>3x + 6x = - 12 - 9</em>
<em>9x = - 21</em>
<em>x = - 21⁽³/9</em>
<em>x = - 7/3</em>
<em>x = - 2 1/3</em>
<em />
<em>12x + 20 = 2x</em>
<em>12x - 2x = - 20</em>
<em>10x = - 20</em>
<em>x = - 20/10</em>
<em>x = - 2</em>
<em />
<em>Good luck !</em>
Answer:
Step-by-step explanation:
1. Subtract 7 on both sides
2. multiply by 4 on both sides
3. v = 4
Answer:
x = 4 or x = -10 for equation x^2 + 6x = 40
Step-by-step explanation:
x^2 + 6 = 40
x^2 = 40 - 6
x^2 = 34
x = root(34) or x = -root(34) but this is not in the answer choice.
is it x^2 + 6x = 40
x^2 + 6x + 9 = 40 +9
(x + 3)^2 = 49
x + 3 = 7 or x + 3 = -7
x = 4 or x = -10
