Answer: X=2

Step-by-step explanation: you want to distribute the 2 to the 3x and 4. That will give you 6x+8 now you want to subtract 8 from both sides. That will give you 6x=12 and you divide both sides by 6 and your final answer should be X=2. :)

Solve for x write the smaller solution first and the larger solution second. Round to two decimal places (x+8)^2-7=0

Answer:

x ≈ - 10.65, x ≈ - 5.35

Step-by-step explanation:

Given

(x + 8)² - 7 = 0 ( add 7 to both sides )

(x + 8)² = 7 ( take the square root of both sides )

x + 8 = ± $\sqrt{7}$ ( subtract 8 from both sides )

x = - 8 ± $\sqrt{7}$ , thus

x = - 8 - $\sqrt{7}$ ≈ - 10.65

x = - 8 + $\sqrt{7}$ ≈ - 5.35
