The expression -3m - [2m + (5 - m)] + 7 was simplified as 2 - 4m. Without simplifying, explain how you can show that it has been simplified correctly.

Step-by-step explanation:

g(m) = 0

2-4m=0

2=4m

2/4=m

1/2=m(1

p(1/2)= -3(1/2) - { 2(1/2) + (5- 1/2) } +7

= -3/2 - { 1 + 9/2} +7

= -3/2 - ( 11/2) +7

=-14/2 +7

= -14 + 14 /2

= 0/2

= 0...

since p(m)= 0,

we can say that g(m) is a factor of p(m)

hence, it has been simplified correctly...

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
