Answer:

90

Step-by-step explanation:

First you do s^2. In this case s is 3 and 3x3=9. Then multiple 9 by r. 9x2=18. Finally, multiply 18 by t. 18x5=90. The solution is 90

Step-by-step explanation:

4.5(9+d)-6

  • 5(9+3)-6
  • 5×12-6
  • 54

6.3h-j

  • 3×8-11
  • 13

8.r(s)²(t)

  • 2(3)²(5)
  • 2×9×5
  • 90
