Neil is going to make concrete. He is going to use 180 kg of cement 375 kg of sand 1080 kg of stone. Cement, sand and stone are sold in bags, shown in the table. Neil already has 15 bags of cement, 22 bags of sand and 18 bags of stone. Work out what bags he needs to buy to make the concrete.

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

answer is (b.
