Answer:

60=2(20)+2x

x=10

Step-by-step explanation:

First, let's write some equations. I wrote 60=2(20)+2x, where x is the length of the room. To solve, first multiply 2 times 20 for 40 (60=40+2x). Then, I subtracted 40 from both sides (20=2x). Finally, I divided on both sides by 2 (10=x).

Synthetic division for x^2+10x+21/x+3
asambeis [7]
X^2+10x+21/x+3?  If you meant (<span>x^2+10x+21)/(x+3), please note that those parentheses are essential.

If you wish to divide </span><span>x^2+10x+21 by (x+3) using synth. div., use the divisor -3:
 
                                        _______________
                                   -3 /    1      10      21  
                                                     -3      -21
                                         -----------------------
                                              1       7        0

Since the remainder is 0, (x+3) is a divisor of </span><span>x^2+10x+21, and the other factor is (1x + 7).</span><span>

Mr. Corbin measures the lengths of three branches. The first branch
anygoal [31]

Answer:

2nd branch > 1st branch > 3rd branch

or

\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}

Step-by-step explanation:

Length of First branch = \frac{2}{3} foot

Length of second branch = \frac{2}{2} foot

Length of third branch = \frac{2}{8} foot

Let us convert the fractions in decimal forms:

1.\  \dfrac{2}{3} = 0.67

2. \dfrac{2}{2} = 1

3.\  \dfrac{2}{8} = \dfrac{1}{4}=0.25

It can be clearly seen that 1 is the largest value among the three values.

So, 2nd branch is the largest.

Now, let us have a look at the values of first and third branches:

0.67 and 0.25.

Clearly, 0.67 is greater than 0.25.

So, the correct order is:

2nd branch > 1st branch > 3rd branch

OR

We can use other method to see it.

Here, all the 3 fractions have same numerator.

So, denominator can help us decide the which fraction has a large value.

If numerator is same, the larger denominator will have smaller fractions.

The denominators are 2, 3 and 8.

8 > 3 > 2

So, the answer is

2nd branch > 1st branch > 3rd branch

or

\dfrac{2}{2} > \dfrac{2}{3} > \dfrac{2}{8}
