find the grouping method to factor the polynomial in the box completely. Use the caret symbol (^) to write the exponent; for exa

sineoko [7]

We start with the polynomial

3x^4 + 12x^3 +27x

Now we search for the common term, in this case it is 3x and factor it out:

3x(x^3+4x^2+9)

Notice that x^3+4x^2+9 cannot be factored anymore then the factorization of the polynomial is:

3x(x^3+4x^2+9)

Roger can run one mile in 18 minutes. jeff can run one mile in 15 minutes. if jeff gives roger a 1 minute head start, how long w

gladu [14]

Alright, lets get started.

Roger can run one mile in 18 minutes.

Jeff can run one mile in 15 minutes.

Suppose in x minutes, they both will catch up.

Roger runs in 18 minutes = 1 mile

So, Roger will run in 1 minute = $\frac{1}{18}$ miles

So, Roger will run in x minutes = $\frac{x}{18}$ miles

Jeff runs in 15 minues = 1 mile

So, Jeff will run in 1 minute = $\frac{1}{15}$ mile

As Jeff gives roger a 1 minute head start, means Jeff will have x-1 minute time to run

So, Jeff will run in (x-1) minute = $\frac{x-1}{15}$

As both are cathing up means they both runs same distance, means

$\frac{x}{18} =\frac{x-1}{15}$

Cross Multiplying

$15 x = 18x - 18$

$3 x = 18$

x = 6 minutes

So for calculating distance = $speed * time$

Distance = $\frac{1}{18} *6 = \frac{1}{3}$ miles

It means it will take 1/3 or 0.33 miles before jeff catches up to roger. : Answer

Hope it will help :)

The romans marched 500 meters in 4 hours. For the next 4 hours they tripled their pace. What was the total distance traveled by

lara31 [8.8K]

Distance traveled during the first 4 hours: 500 m Note that the rate here was 125 m/hr.

Distance traveled during the next four hours: 3(125 m/hr)(4 hr) = 375 m

Total distance traveled: 500 m + 375 m = 875 m

Answer:

x = 3.873 units

or x = $\sqrt{15}$ units

Step-by-step explanation:

Hypotenuse = 4 , x = height of this isosceles triangle.

base is 2,

so Use Pythagorean Theorem.

x^2 + 1^2 = 4^2

x^2 = 4^2 - 1^2

x^2 = 16 - 1 = 15

x = root(15) =
