Solve for m. 3m+7/2=−2m+5/2 a.-1 b.-1/5 c.6 d.6/5

To solve this we must isolate x which involves having the variables on one side and the numbers on the other.

First add 2m to both sides

3m+7/2=-2m+5/2

5m+7/2=5/2

Then we subtract 7/2 from both sides

5m+7/2=5/2

5m=-1

Finally we divide both sides by 5

5m/5=-1/5

Our final answer is -1/5

So the answer is B

Hope this helps!

step-by-step explanation:

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
