Answer:

16

Step-by-step explanation:

To evaluate an expression we need to substitute for k = 3 and j= 10 into the expression given

  (5k − j) 2 + 2k

= (5*3 −10)*2 +2*3, see k write 3, see j write 10

= (15 -10)*2 + 6, multiply 5*3 and 2*3

= 5*2 + 6 , subtract the numbers in parenthesis (15-10)=5

= 10 + 6, multiply 5 and 2 first, then add 10 and 6

= 16
