Answer:
y = 3 x + 3 is the required equation.
let's check it
when x=1
y=3×1+3=6 true
when x=2
y=3×2+3=9true do similarly like this.
Answer:
x=144

Answer:
SA = 288 cm
Step-by-step explanation:
l = 12
w = 4
h = 6
SA = 2lw + 2wh + 2lh
SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)
SA = 96 + 48 + 144
SA = 288
