You distribute a 3/4 wherever you see a v
Use PEMDAS order of operations (parenthesis, exponents, multiply, divide, add, subtract)

12*3/4(32*9/16-8) 
12*3/4(18-8)
12*3/4(10)

PLEASE HELP!!!! IN NEED OF IT
prisoha [69]

Answer:

Below in bold.

Step-by-step explanation:

This is a regular polygon so all sides are congruent, therefore:

The perimeter of the polygon = 6*34 = 204 units.

We can divide the polygon into 6 conguent triangle with height 30 and base 34.

So area of 1 triangle = 1/2*34*30 = 510.

So area of the polygon = 6 * 510 = 3060 unit^2.

Perimeter of the polygon = 6*34 = 204 units.

Answer:

D. 5.0

Step-by-step explanation:

When the ball hit the ground, height h =0

So,

h= -4.9t² + 25t

0 = -4.9t² +25t

t(-4.9t+25)=0

t=0 (start) , and -4.9t+25=0,   4.9t =25,    t≈5.1(finish)
