The formula for volume of this rectangular prism is: v=2x^3+17x^2+46x+40 find an expression for the missing side length. Show al

vodka [1.7K]

Answer:

the missing side length is $(2x+5)$

Step-by-step explanation:

we know that the volume of the rectangular prism is equal to

$v=LWH$

In this problem we have

$v=L(x+4)(x+2)$

$v=2x^3+17x^2+46x+40$

using a graphing tool find the x-intercepts of the function

see the attached figure

The x-intercepts are

$x=-4, x=-2.5, x=-2$

$v=2(x+2.5)(x+4)(x+2)$

$v=(2x+5)(x+4)(x+2)$

therefore

the missing side length is $(2x+5)$

9. Carlos is taking a road trip. So far he has traveled 120 miles at a constant speed of 60 mph. His

Svetradugi [14.3K]

Answer:

Part 1) 300 miles

Part 2) 420 miles

Part 3) 600 miles

Step-by-step explanation:

we have

$d(x)=60x+120$

where

d(x) is the distance in miles

x is the time in hours

Part 1) How many miles will he have traveled after 3 more hours?

we know that

To find the distance, substitute the value of x in the function

For x=3 hours

$d(3)=60(3)+120=300\ mi$

For x=3, d(x)=300

That means -----> After 3 hours Carlos has traveled 300 miles at a constant speed of 60 mph

Part 2) How many miles will he have traveled after 5 more hours?

we know that

To find the distance, substitute the value of x in the function

For x=5 hours

$d(5)=60(5)+120=420\ mi$

For x=5, d(x)=420

That means -----> After 5 hours Carlos has traveled 420 miles at a constant speed of 60 mph

Part 3) How many miles will he have traveled after 8 more hours?

we know that

To find the distance, substitute the value of x in the function

For x=8 hours

$d(8)=60(8)+120=600\ mi$

For x=8, d(x)=600

That means -----> After 8 hours Carlos has traveled 600 miles at a constant speed of 60 mph
