Answer:The solutions are -3 and -6
Explanation:First we would need to put the equation in standard form which is:
ax² + bx + c = 0
This can be done as follows:
x² + 18 = -9x
x² + 9x + 18 = 0
By comparison, we would find that:
a = 1
b = 9
c = 18
Now, to get the roots, we would use the quadratic formula shown in the attached image.
By substitution, we would find that:
either x =

or x =

Answer:
Step-by-step explanation:
<u>Required equation</u>
<u>Solving for x</u>
- 12x - 8x = 10 + 18
- 4x = 28
- x = 28/4
- x = 7
Answer:
NO=22.6
Step-by-step explanation:
NO=MO+MN
after substituting MO and MN,
NO=15+7.6
=22.6
also, the problem says to answer with only the number, so just type 22.6!
Answer:
x= 1/3
Step-by-step explanation:
simplify so you can isolate x quicker: 2x-5=5x-6
subtract 2x from both sides: -5=3x-6
add 6 to both sides: 1=3x
divide both side by the 3 to isolate x: 1/3=x
