4(4) - 2(7) = 20
16 - 14 = 20
2 = 20 (wrong)

• (3, 4)
4(3) - 2(4) = 20
12 - 8 = 20
4 = 20 (wrong)

• (2, -7)
4(2) - 2(-7) = 20
8 + 14 = 20
22 = 20 (wrong)

• (7, 4)
4(7) - 2(4) = 20
28 - 8 = 20
20 = 20 (correct)

Step-by-step explanation:

If you're converting from another base, just multiply each digit, then add up the numbers:

ones digit × 8^0,

tens digit × 8^1

hundreds × 8^2

see image.

The second problem gives you a new operation. Follow the rule by squaring the first number and taking away the first×second. Do the parenthesis first!

Solve by completing the square x^2-6x-4=0
Vesna [10]

Answer:

x = 3 ± \sqrt{13}

Step-by-step explanation:

x² - 6x - 4 = 0 ( add 4 to both sides )

x² - 6x = 4

To complete the square

add ( half the coefficient of the x- term)² to both sides

x² + 2(- 3)x + 9 = 4 + 9

(x - 3)² = 13 ( take square root of both sides )

x - 3 = ± \sqrt{13} ( add 3 to both sides )

x = 3 ± \sqrt{13}
