A. 12x^4 + 10x^3 - 22x^2 - 15x

Step-by-step explanation:

(6x^2 - 4x - 5)(2x^2 + 3x)

2x^2 (6x^2 - 4x - 5) + 3x(6x^2 - 4x - 5)

12x^4 - 8x^3 - 10x^2 + 18x^3 - 12x^2 -15x

12x^4 + 10x^3 - 22x^2 - 15x

If a bike travels 5 miles in 20 minutes, how long does it take to travel 25 miles?
faust18 [17]

Answer:

100 minutes

Step-by-step explanation:

To solve this, we can make a proportion.

The bike travels 5 miles in 20 minutes, and 25 miles in x minutes

5/20=25/x

Cross multiply

5*x=20*25

5x=500

Divide both sides by 5. This will cancel out the 5, and leave x by itself.

5x/5=500/5

x=100

There are 60 minutes in 1 hour. If we subtract 60 from 100,

100-60=40

So, this is also equivalent to 1 hour and 40 minutes.

It takes 100 minutes, or 1 hour and 40 minutes, to travel 25 miles.

nadezda [96]
Hi there

To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question

While the amount invested at 5% is
6000-4000=2000

Good luck!
