If a*b=a^2+b, write the values of 4*(3*5)

30

Step-by-step explanation:

Evaluate 3* 5 first , that is

3* 5 = 3² + 5 = 9 + 5 = 14 , then

4* 14

= 4² + 14

= 16 + 14

= 30

she played for 18.75 hours.

step-by-step explanation:

if she played 2/4 of a hour on tuesday. and there is 60 minutes in an hour and 60 divided by 4 is 7.5. and she played 2/4 of an hour on thursday then again 60 divided by 4 is 7.5, you add 7.5+7.5=56.25. now you have to do 1/4 of an hour, it equals 3.75. now you have to add them all up. 3.75+7.5+7.5=18.75
