1. a student has several boxes of penils in his backpack. each box contains 12 pencils. the student
takes out 1 pencil for himself and gave 3 penils to his friends to use.
which function show the relationship between y, the total number of pencils remaining in his backpack
and x, the number of boxes in his backpack?
a. y = 12x +3
b. y = 128-4
c. y = 12x
d. y = 3x

I think it is A because 12 is the slope and 3 is just b... try y = mx + b

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
