The volume of a rectangular prism is computed by a formula volume = length times width times height. So base on your given the volume is represented by x^3+11x^2+20-32 and the width is x-1 and height is x+8 the length is x+4 i hope i answered your question
Answer:
The final cost is $207.65
Step-by-step explanation:
Regular price of the chair is $349
with 30% off,
(30/100)*$349 = 0.3*$349
= $104.70
actual cost is $349 - $104.70 = $244.30
For a customer using 15% off coupon
15% of actual cost
(15/100)*244.30 = 0.15*244.3
= $36.65
Final cost is $244.30 - $36.65
= $207. 65

Answer:
They could cover 90 kilometres in 6 hours, after the terrain changed.
Step-by-step explanation:
Their speed, when they were traversing through the marsh, is:
speed = distance/time
s = 20 km / 4hr
s = 5 kmph
If their speed tripled, then it will be: 5*3 = 15 kmph
distance = speed * time
d = 15 km/h * 6h
d = 90 km
They could cover 90 kilometres in 6 hours, after the terrain changed.
2x+1=5x-20
you want to find the x value so you want to isolate x to do this you have to subtract 2x on both sides. After you have accomplished this you add 20 on both sides once again and then you divide what your answer from what you added by three.
2x+1=5x-20
-2x -2x
________
1=3x-20
+20 +20

21/3=3x/3
7=x
