Write the quadratic equation in general form. (x - 3)^2 = 0 a) x^2 + 9 = 0 b) x^2 + 6x + 9 = 0 c) x^2 - 6x + 9 = 0

C

Step-by-step explanation:

(x - 3)² = 0

(x - 3)(x - 3) = 0

x(x - 3)  -3(x - 3) = 0

x² - 3x  -3x + 9  = 0

x² - 6x + 9  = 0

134.6 us dollars

step-by-step explanation:

1 us dollar = 1.33 canadian dollars

so, 150 us dollars = 150 × 1.33 = $199.5.

in canada, the money mitchell spent = 20 canadian dollars.

remaining canadian dollars with him = 199.5 - 20 = 179.5.

after mitchell returned to us, he exchanged the remaining canadian dollars to us dollars.

179.5 canadian dollars = 179.5 × 0.75 = 134.6 us dollars.
