I need help with this one I try doing it and I don’t think I’m getting it

C) P=56cm^2

Step-by-step explanation:

P=(a*h)/2 a=14, h=8

P=(14*8)/2

P=112/2

P=56

c

Step-by-step explanation:

area=1/2*14*8=56 cm^2

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.

he has now walked a total of what?

if i know what this is maybe i can
