Find all real solutions of the equation. ( 2 b + 4 ) 2 − 12 = 0

B = 2

Step-by-step explanation:

( 2 b + 4 ) 2 − 12 = 0

Distribute..

2b+4(2)-12=0

combine like terms

2b+8-12=0

2b-4=0

Now solve this simple 2 step equation...

2b-4=0

+4=+4     <- add 4 to both sides

2b=4

/2  = /2    <- divede both sides by 2

B = 2

Step-by-step explanation:

Find all real solutions of the equation. ( 2 b + 4 ) 2 − 12 = 0

( 2 b + 4 ) 2 − 12 = 0

4b + 8 - 12 = 0

4b - 4 = 0

4b = 4

b = 1

check

(2*1+4)*2-12=0

12 - 12 = 0

0 = 0

the answer is good

1. 3

2. 4

3. 1

hope this ! have a great day.

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
