Answer:
x = x = 9 ±
or x ≈ 12.61 or x ≈ 5.39
Step-by-step explanation:
x² - 18x + 68 Solve by completing the square.
x² - 18x = - 68
Now complete the square and add that number to both sides of the equation.
1/2 (of the coefficient of the x term)² = (1/2 · -18)² = 81 .
x² - 18x + 81 = -68 + 81
(x - 9) (x - 9) = 13 Now find the square root of both sides
=
Solve
x - 9 = ±
Solve for x
x = 9 ±
x = 9 +
or x = 9 -
x ≈ 12.61 or x ≈ x 5.39
Answer:
0.35*4=1.40
Step-by-step explanation:
Think of doing 35*4 but dividing the result by 100, or 2 decimal places to the left:
35*4 = 35*2*2 = 70*2 = 140
140/100 = 1.40
So, 0.35*4=1.40
