What values of b satisfy 4(3b + 2)2 = 64?
Vikentia [17]
Given the equation 4(3b + 2)² = 64, dividing both sides of the equation by 4, we have (3b + 2)² = 16 and getting the square root of both sides, (3b + 2) = 4 and (3b + 2) = -4 We can solve for b for each equation and have 3b = 2 | 3b = -6 b = 2/3 | b = -2 Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>

Tems11 [23]

Answer:

1. a=85.8 c=89.2

2. x=29.7 8x=2937. 3

Step-by-step explanation:

2. 8x+x+27°+66°=360°

8x+x=360°-66°-27°

9x=267 >Then divide both sides with 9

x=<u>29</u><u>,</u><u>666666</u><u>.</u><u>.</u><u>.</u>

<u> </u><u> </u>

=8X

=8 (29,66666...)

=237,333...

1. 6X+4X+32°=180°

10X=180°-32

10X=148° >divide both sides with 10

X=14.8

A=6x c=4x+32

=6(14.8) =4(14.8)+32

= 88.8 =91.2
