Answer:
8x^3-7x^2-11x+9
Step-by-step explanation:
(8x^3-5x-1)-(7x^2+6x-10)
remove unnesasary ( )
8x^3-5x-1 -(7x^2+6x-10)
the distribute
8x^3-5x-1 -7x^2-6x+10
combine like terms
8x^3-11x+9-7x^2
use the communative property to reorder the equation
8x^3-7x^2-11x+9
Answer:
0.25×308=$77
185-77=$108
108/0.50×1
=216photos
Total photos=216+308
=524photos

Step-by-step explanation:
Answer:
The solution is x =2 for the given equation 
Step-by-step explanation:
We need to find the solution for x in the given equation.

Solving:
Subtract
from both sides

Taking square on both sides

Putting values and solving

Verifying the solution by putting values of x in given equation
Putting x=18

So, x=18 is not solution o given equation.
Putting x = 2

So, x=2 satisfies the equation
The solution is x =2 for the given equation
