Answer:
b^2+17
Step-by-step explanation:
2^3 is 8 (2*2*2=8)
b^2 stays the same bcz its a variable and we don't know its value
3^2 is 9 (3*3=9)
SO just substitute,
8+b^2+9
b^2+17
So first u would need tto know how many hours are in a day so there are 24 hours in a day so u would do 45x72 cause there are 72 hours in 3 days.

Answer:
The price of the computer is $1,152
Step-by-step explanation:
Let the price of the computer be $x
The first boy boy had 7/8 of this amount, the amount he has is thus 7/8 × $x = 7x/8
The second boy had 5/6 of what the first boy had. The amount of money he has is thus 5/6 × 7x/8 = 35x/48
Now, the addition of what they have is $696 more than what they need to pay. This amount is x+ 696
Mathematically, this can be represented as;
7x/8 + 35x/48 = x + 696
(42x + 35x)/48 = (x + 696)
77x/48 = (x + 696)
77x = 48(x + 696)
77x = 48x + 33408
77x - 48x = 33408
29x = 33, 408
x = 33,408/29
x = $1,152
