<h3>Answer:</h3>

2 seconds

<h3>Explanation:</h3>

Equation: g(x) = -16x² + 64x + 80

<u>In order to find the maximum</u>:

vertex : -b/2a

           = -64/2(-16)

           = -64/-32

           = 2

Maximum Height:

= -16(2)² + 64(2) + 80

= 144 ft

The vertex should be maximum as a is negative and parabola opening downwards

So

x coordinate of vertex

  • -/2a
  • -64/-32
  • 2

y coordinate is max height

  • -16(2)²+64(2)+80
  • -16(4)+128+80
  • -64+128+80
  • 128+16
  • 144ft

Vertex at (2,144)

Using the distributive property

7(a+b)=7a+7b

therefore

<u>the answer Part A is</u>

9-----> A

<u>Part R)</u>  4(5+x)=20+

Using the distributive property

4(5+x)=20+4x

therefore

<u>the answer Part R is</u>

14-----> R

Using the distributive property

3(2x+9)=6x+27

therefore

<u>the answer Part Y is</u>

4-----> Y

Part S)  8(3x+1)=+8

Using the distributive property

8(3x+1)=24x+8

therefore

<u>the answer Part S is</u>

23-----> S

<u>Part O)</u>  a(4+b)=+ab

Using the distributive property

a(4+b)=4a+ab

therefore

<u>the answer Part O is</u>

17-----> O  

<u>Part E)</u> x(y+10)=+10x

Using the distributive property

x(y+10)=xy+10x

therefore

<u>the answer Part E is</u>

3-----> E

<u>Part I)</u> 2(7x+4y)=14x+

Using the distributive property

2(7x+4y)=14x+8y

therefore

<u>the answer Part I is</u>

20-----> I

<u>Part D)</u> 6(9+5x)=54+

Using the distributive property

6(9+5x)=54+30x

therefore

<u>the answer Part D is</u>

10-----> D  

<u>Part W)</u> x(a+3b)=+3bx

Using the distributive property

x(a+3b)=ax+3bx

therefore

<u>the answer Part W is</u>

18-----> W

<u>Part E)</u> a(8x+2y)=8ax+

Using the distributive property

a(8x+2y)=8ax+2ay

therefore

<u>the answer Part E is</u>

7-----> E

<u>Part T)</u> 0.5(4a+10)=2a+

Using the distributive property

<u>Part T)</u> 0.5(4a+10)=2a+5

therefore

<u>the answer Part T is</u>

1-----> T

<u>Part R)</u> (2/3)(12+9y)=8+

Using the distributive property

(2/3)(12+9y)=8+6y

therefore

<u>the answer Part R is</u>

(3m - 4n - 7) - (8m + n - 6)

3m - 8m  = - 5m
-4n - n = -5n
-7 - (-6) = -7 + 6 = -1

-5m - 5n - 1 is your answer
