Answer:

\frac{x - 10}{8}

Step-by-step explanation:

\frac{3x}{8} - \frac{x + 5}{4}

The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.

Thus:

\frac{1(3x) - 2(x + 5)}{8}

\frac{3x - 2x - 10}{8}

\frac{x - 10}{8}

Find k. ..................​
Nonamiya [84]

Answer:

k = -10

Explanation:

f(x) = 4x³ - 3kx² + 44x - 30

The divisor is:

  • (x - 2)

Set divisor to zero:

  • (x - 2) = 0
  • x = 2

Insert this into equation.

⇒ 4(2)³ - 3k(2)² + 44(2) - 30 = 210

⇒ 32 - 12k + 88 - 30 = 210

⇒ -12k + 90 = 210

⇒ -12k = 210 - 90

⇒ -12k = 120

⇒ k = 120/-12

⇒ k = -10
