Big rectangle
3x-4 (2x+2) = 6x^2-8x+6x-8
=6x^2-2x-8 = 3x^2-x-4

Small rectangle
(X-3) (x-6) = x^2-3x-6x+18
=x^2-9x+18

Big-small= 2x^2+8x-22 is the area of the shaded region

Caden biked 1 2/5 miles in 1/4 hour. If it is currently 4:00 P.M. and he has to bike 14 miles. At what time will he be finished?
Arturiano [62]

Answer:

He will finish the biking at 6:30 pm

Step-by-step explanation:

1/4 hour is same as 1/4 * 60 = 15 minutes

1 2/5 miles is same as 1.4 miles

He bikes 1.4 miles in 15 minutes

then he will bike 14 miles in 15 * 10 = 150 minutes

150

minutes is same as 2 hours 30 minutes

Adding this to 4 pm, we will get;

6:30 pm

A ________ is a whole number that divides another whole number with a remainder of 0
Brut [27]

It's a factor. This concept is widely used throughout algebra, and you'll probably bump into it through the end of high school and beyond.

A common use is expressing a term in <em>prime factorization</em>, or reducing a number to its most base parts- primes. For example:

20 = 4 * 5 = 2 * 2 * 5

Of course, a number like 13 which is already prime is made up of itself and 1. <em>Factors do not have to be primes.</em> 20 is also reducible through combinations of 1, 2, 4, 5, 10, and 20. Prime factorization is just a handy example.

Basically, factors multiply with each other to create other numbers, and numbers can be reduced down to their factors.
