I just want to reccomend desmos, it really helped me with graphing because im not so good at it
But what I got is:
x-4y=-18
x=-18+4y
Root(-18,0)
Y-intercept: (0, 9/2)
What part do you have trouble with
Two plus ten times eight
(2+10)*8 = 96
First do (30×20)/2 + 20×25 + 35×42 + (42×25)/2
it should give you a total of 2795 cm
