Answer:
52 Sides
Step-by-step explanation:
Octagons have 8 sides so 3 x 8 = 24
Pentagons have 5 sides so 4 x 5 = 20
Trapezoids have 4 sides so 2 x 4 = 8
Add it all up and it equals 52 sides in total

when you multiply fractions you multiply trait across meaning you do 5*1 and 2*2 which leaves you with 5/4 and that is equivalent to 1 &1/4
Answer:
The ball travel horizontally 37 feet before it hits the ground
Step-by-step explanation:
we have

where
x ----> is the horizontal distance in feet
A ---> is the altitude of the ball, in feet.
we know that
When the ball hit the ground, the altitude of the ball is equal to zero
so
For A(x)=0

solve the quadratic equation
The formula to solve a quadratic equation of the form
is equal to
in this problem we have

so
substitute in the formula
therefore
The ball travel horizontally 37 feet before it hits the ground
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24
