Perimeter= 2(L+W)
2(L+W)=28
2(2W-1+W)=28
2(3W-1)=28
6W-2=28
6w=30
W=5

in short the answer is 5

Which of the following is equal to the rational expression when x*-2 or 3? X^2 +5x+6 X^2-X-6

trasher [3.6K]

Answer:

Step-by-step explanation:

x=-2, x=3

---------------

x^2+5x+6=(-2)^2+5(-2)+6=(-2)(-2)-10+6=4-10+6=-6+6=0

x^2+5x+6=3^2+5(3)+6=9+15+6=24+6=30

---------------------------------------------------------------

x^2-x-6=(-2)^2-(-2)-6=4+2-6=6-6=0

x^2-x-6=3^2-3-6=9-3-6=6-6=0

John borrowed $ from bank for 3 years at a rate of 10%

garik1379 [7]

<h3>Given:</h3>

P= $12500
R= 10%
T= 3 years

P= Principal amount
R= Rate of interest
T= Time period

The simple interest
The total amount paid

<h3>Solution:</h3>

$\large\boxed{Formula: I= \frac{PRT}{100}}$

First, we'll have to multiply, principal amount (12500), rate (10) and time period (3).

$12500×10×3$

$=375000$

Now, we'll have to divide the amount (375000) by 100.

$\frac{375000}{100}$

I=$3750

Now, we can find the total amount paid.

$\large\boxed{A=SI+P}$

Let's substitute according to the formula.

$A=3750+12500$

A=$16250

Therefore, simple interest is $3750 and $16250 was paid in total.

How much is 110 hours in days and hours

eimsori [14]

4 days and 14 hours.

Method I used:

1. Do 110÷24 and you should get 4.58333333333. Ignore the numbers after the decimal point, and write down 4 as your number of days.
2. Do 4×24 (you should get 96) and subtract that from 110 (you'll get 14). The difference will be the number of hours.

Hope I helped! <3
