Answer:
(x^3+3x^2+x+1)+(2x^3-2x^2-2x+2)
3x^3 + x^2 - x + 3
I think I simplified it completely. Hope this helps! Good luck! :)
Henry paid a total of $360 for the dishwasher: $20 + (10 x $34) = $20 + $340= $360
Therefore he paid $40 extra which we place over the original amount of the dishwasher:

Dividing 1 by 8 we get .125 which, when changed to a percentage becomes 12.5%
Henry paid a yearly interest rate of 12.5%
Answer:
3.33%
Step-by-step explanation:
Factory measure=330 ml
Actual measure=341 ml
Difference between actual measure and factory measure is error
Difference=341 ml-330 ml=11 ml
Error (in ml)=11 ml
Percentage error=100* Error/Factory measure
Percentage error= 100*
Percentage error=3.33%
Therefore, the percentage error in the content is 3.33%
Answer:

Step-by-step explanation:
The square base of each prism has a side length of 18 inches. The height of each prism, h, can be found using the function, where V is the volume of the prism.
So, V = 18² × h = 324h
⇒ h =
.......... (1)
Now, given that the total height of the box, b, can be found using the function b(h) = xh, where x is the number of square-based prisms in a specific box.
Therefore, the box having 4 square prism will have height
b(h) = 3h
⇒ b(V) =
{From equation (1)}
⇒
(Answer)
The scale factor would be 1:1 (1) for this question
