Answer 2

Answer:

$f(x) = 3k {x}^{2} - 5x \\ d(x) = x - 4 \\ f(x) \div d(x) = 10 \\ that \: is \: r(x) = 10. \\ x - 4 = 0 \\x = 4 \\ f(4) = 10. \\ 3k {4}^{2} - 5(4) = 10 \\ (3 \times 16 \times k) - 20 = 10 \\ 48k = 10 + 20 \\ k = 30 \div 48 \\ k = 5 \div 8 \\ k = 0.625.$

Step-by-step explanation:

therefore the value of k is 0.625 or 5/8.
