Question

Please help number 42

Answer 1

All I know

Step-by-step explanation:All I know is that you have to distribute the top so 5{2k - 3} so that would be 10k-15 and then -3{k+4} would be -3k -12 hopefully this helps you out a littble bit so the top completely is 7k-27

Answer 2

41/4 = 10.25

Explanation:

Put -2 where k is and do the arithmetic.

`(5(2k-3)-3(k+4))/(3k+2)=(5(2(-2)-3)-3(-2+4))/(3(-2)+2)\\\\=(5(-4-3)-3(2))/(-6+2)=(5(-7)-6)/(-4)=(-35-6)/(-4)\\\\=(41)/(4)=10.25`
