Answer:
y+1=-2(x-3)
Step-by-step explanation:
y-y1=m(x-x1)
y-(-1)=-2(x-3)
y+1=-2(x-3)
-53
Step-by-step explanation:

Answer:
864 ft^2
Step-by-step explanation:
Surface area equation is the same as the one used in the other problem; S=(1/2)lP + B
one side is 20 x 14 = 280
another side is 12x14 = 168
another side is 16x14 = 224
the triangle bases are A=(1/2)bh
(1/2)12 x 16 = 96
2(96) = 192
Add all sides together 192 + 224 + 280 + 168 = 864

so.... notice, using the p/q factors, we ended up using 3/1 or just 3, so the root of x = 3, which gives us the factor of x-3 then
then you factor the quadratic, then set f(x) to 0, and solve each for "x"
