When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,
y=kx
Plug in (5,100)
100=k(5)
K=20

A=2(LW+LH+WH)
A=2((7/8)(1/3)+(7/8)(2/5)+(1/3)(2/5))
A=2(7/24+14/40+2/15)
A=14/24+28/40+4/15
A=7/14+7/10+4/15 210
A=(105+147+56)/210
A=308/210
A=(210+98)/210
A=1 98/210
A=1 7/15
Answer:
Step-by-step explanation:
y - 8 = 2(x - 2)
y - 8 = 2x - 4
y = 2x + 4
