Answer:

A and D

Step-by-step explanation:

Given

x² + 20 = 9x + 2 ( subtract 9x + 2 from both sides )

x² - 9x + 18 = 0 ← in standard form

(x - 3)(x - 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3

x - 6 = 0 ⇒ x = 6

Answer:

6 and 3

Step-by-step explanation:

x^2 - 9x + 18 = 0

(x-6)•(x-3)=0

if x-6 = 0 then x = 6

and if x-3= 0 then x = 3

Barb solved the following equation: 4(3x – 12) = 5(2x + 6)
katrin2010 [14]

Answer:

4(3 * 39 – 12) = 5(2 * 39 + 6)

x = 39


Step-by-step explanation:

4(3x – 12) = 5(2x + 6)

(12x - 48) = (10x + 30)

12x - 10x = 30 + 48

2x = 78

2x/2 = x

78/2 = 39

x = 39
