solve the following equations
3m = 2(m - 3)^2

m = 6 or m = 3/2

Step-by-step explanation:

Solve for m over the real numbers:

3 m = 2 (m - 3)^2

Expand out terms of the right hand side:

3 m = 2 m^2 - 12 m + 18

Subtract 2 m^2 - 12 m + 18 from both sides:

-2 m^2 + 15 m - 18 = 0

The left hand side factors into a product with three terms:

-(m - 6) (2 m - 3) = 0

Multiply both sides by -1:

(m - 6) (2 m - 3) = 0

Split into two equations:

m - 6 = 0 or 2 m - 3 = 0

Add 6 to both sides:

m = 6 or 2 m - 3 = 0

Add 3 to both sides:

m = 6 or 2 m = 3

Divide both sides by 2:

m = 6 or m = 3/2

Hey I don't get the ww part but for the first part the answer is

Height after 7 week=34

Find the Equation:

H=2w+20

Plug in 7 to the equation

h=2(7)+20

h=14+20

h=34
