Simplify 4(6 - 2x) - 3(3 - 4x)

a)15 - 6 x
b)15 - 20 x
c)4 x + 15

c) 4x + 15

Step-by-step explanation:

4(6-2x) - 3 (3-4x) is the given equation

The first thing that needs to be done is to distribute

24-8x - 9+12x    (Remember a negative + negative = positive)

The second step is combing like terms.

24-9=15     -8x+12x=4x

The last step is making the equation.

4x + 15

(3x-8) or (3x+8)

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
