Ugo [173]2 years ago

5 0

Answer:

Step-by-step explanation:

2x^2-6x+10=0

2(x^2-3x)+10=0

2(x-(3/2))^2-9/4)+10=0

2(x-(3/2))^2+10-9/2=0

2(x-(3/2))^2+(20-9)/2=0

2(x-(3/2))^2+11/2=0

2(x-(3/2))^2=-11/2

square is always positive so there is no solution

Answer:

C, x ≥ 14.96

Step-by-step explanation:

Step 1: Add 3.408 to both sides.

2.2x − 3.408 (+ 3.408) ≥ 29.504 (+ 3.408)

2.2x ≥ 32.912

Step 2: Divide both sides by 2.2.

2.2x (÷ 2.2) ≥ 32.912 (÷ 2.2)

x = 14.96
