Answer:

x^2-x-12

Step-by-step explanation:

You can use the formula of FOIL, you go to each factor in the parenthesis and multiply by the other factors, the inside will first be x^2 then the middles will be 3x and -4x and the outside will be -12 then you simplify by combining like terms making the middle -x.

Make n the subject of m= 4n-gn+1
Misha Larkins [42]

Answer:

n = (m-1)/(4-g)

Step-by-step explanation:

m= 4n-gn+1

Subtract 1 from each side

m-1= 4n-gn+1-1

m-1 = 4n -gn

Factor out n

m-1 = n(4-g)

Divide each side by (4-g)

(m-1)/(4-g) =  n(4-g)/(4-g)

(m-1)/(4-g) =  n

n = (m-1)/(4-g)
