Answer:
2m+3x=9
Step-by-step explanation:
12(m+3x)=18(x-3)
distribute
12m+36x=18x-54
simplify
12m+18x=54
more simplify
2m+3x=9
I believe thats all you can do
Step-by-step explanation:
1/2 cannot be simplified, however you can solve this question by shading in the other half of the left square, and taking away a shade on the right one :)
Answer: 1,070 cm²
Step-by-step explanation:
25 multiplied by 15 is 375.
15 multiplied by 4 is 60.
25 multiplied by 4 is 100.
Now, we multiply these answers by 2.
375 multiplied by 2 is 750.
100 multiplied by 2 is 200.
60 multiplied by 2 is 120.
Add these all up, and you get your surface area, 1,070.

Answer:
Solutions of x are;
x = -7 + 8i and x = -7 -8i
Step-by-step explanation:
Given the equation: 
Add 96 both sides we get;
Using quadratic formula 
then the solution is given by:
On comparing we have;
a= 1, b =14 and c =113
or
Simplify:
; where i is the imaginary, 
or
Therefore, the solution of x are; x = -7 + 8i and x = -7 -8i
