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
hope it helps.
