This is due in 20 minutes. (100 points) if anyone is good at math, could you please help me? also, I get a lot of people that just write in crazy responses just for points so I'm BEGGING you to not do that. If you have ANY morals can u pls just not do it. You wouldn't want someone to do that to you. So please help? Thank you.

1st

5x²+10x+2x+4

5x(x+2)+2(x+2)

(x+2)(5x+2)

(x+2)=0 and 5x+2=0 is a required answer.

2nd

4x²-16x-5x+20

4x(x-4)-5(x-4)

(4x-5)(x-4) is a required equation.

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

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.
