Which best proves why the expressions 4(x+3) + 2x and 6(x+2) must be equivalent expressions? When x= 3, both expressions have a value of 30.
When x = 5, both expressions have a value of 42.
When x-1both expressions have a value of 18, and when x = 8, both expressions have a value of 60.
When x - 2. both expressions have a value of 15, and when X = 6, both expressions have a value of

answer: idk

step-by-step explanation:

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
