Total sum = 200 + 50 = $250

Total cost for x month  = 200 + 50x

Step-by-step explanation:

Han's cell phone plan cost $200 to start. Then there is a $50 charge each month.

a. What is the total cost (start up fee and monthly charge) to use the cell phone  plan for 1 month?

Total charge for 1 month plan will be the sum of the cell phone plan and the charge for 1 month.

Total sum = 200 + 50 = $250

b. What is the total cost for x months?

Total cost for x month  = 200 + 50x

where

x is the number of months

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
