Which numbers are solutions
2 answers:
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

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
