Answer:
x=3
Step-by-step explanation:
minus 3x on both sides
after you've subtracted 3x from both sides you then need to minus 12 from both sides
Last step is going to be dividing by 2 and you should get the answer of 3
The quadratic formula is .
From the problem, a is 1, b is -1, and c is 12. Plugging in these values gives:
Because there is a square root of a negative number, there is no solution.
The simplified answer is 27m^2
This was rough, but either way I love math haha
Answer:
Step-by-step explanation:
2)
x + 14 = -0.87
x + = -
x + = -
x = - -
x = -
3)
x -8 = 1.5
x - =
x = +
x =
x =
4)
x - = - 7
x - = -
x = - +
x = -
5)
- x = 6
= + x
- = x
- = x
x = -
6)
-33.754 - x = 28.05
-33.754 - 28.05 = x
- 61.804 = x
x = - 61.804
