Answer:

x=6

DO=25

OG=35

Step-by-step explanation:

start by solving the length of DG to find x.

DO+OG=60

(4x-3)+(2x+21)=60

6x+18=60

6x=42

x=7

Now plug in x and solve.

DO=4(7)-3

DO=28-3

DO=25

OG=2(7)+21

OG=14+21

OG=35

Answer:

see below

Step-by-step explanation:

1. 0 = (r + 1)(r + 8)

Using Zero Product Property, r = -1, r = -8

2. h(r) = (r + 1)(r + 8)

= r² + 9r + 8

= (r + 9/2)² - 81/4 + 8

= (r + 4.5)² - 12.25 (Complete the square)

Vertex: (-4.5, -12.25)
