The area of a triangle is found using the formula Area = 1/2 x base x height.
Base = 8
Height = 18.
The area of 1 triangle = 1/2 x 8 x 18 = 72 square units.
There are a total of 4 sides, so total area = 72 x 4 = 288 units ^2
The answer is, (1, -5)...
30÷4=7.5
45÷7.5=6
you will need about 6 gallons of water to fill it.
F(14) would be, 14=1/2x-2
-1 is greater then 1.05 then 1.05 then 1.55
so the answer is C
