The perimeter is just the sum of all of the side lengths.

p=3x+4+x-10+5x-2

p=9x-8

Add up the lengths of the 3 sides.  Starting with x terms, we get 3x + 4 + x - 10 + 5x - 2.  The x terms combined result in 9x and the constants combined result in -8.  The perimeter is thus 9x - 8 units.

Answer:

\sqrt{44} = 2\sqrt{11}

Step-by-step explanation:

Apply pythagorean theorem:

ABD is a right triangle with angle ADB = 90

hence AD = \sqrt{AB^{2} - BD^{2}  } where BD = 10 because it is half of BC

AD = \sqrt{12^{2}-10^{2}  } = \sqrt{44} = 2\sqrt{11}

Rex took out a loan for $5000 and planned to pay it back in 4 years. If he paid $600 in interest for those 4 years, what was the
Gwar [14]

~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\dotfill & \$600\\ P=\textit{original amount deposited}\dotfill & \$5000\\ r=rate\to r\%\to \frac{r}{100}\\ t=years\dotfill &4 \end{cases} \\\\\\ 600=5000(\frac{r}{100})(4)\implies \cfrac{600}{5000(4)}=\cfrac{r}{100}\implies \cfrac{3}{100}=\cfrac{r}{100}\implies \boxed{3=r}

Rina8888 [55]

Answer:

The answer to your question is 48 chairs

Step-by-step explanation:

Data

5 rows- 3 chairs left over

3 rows - 21 chairs left over

Process

1.- Write two equations each for each situation

x = number of rows

y = number of chairs

Equation 1       y = 5x + 3

Equation 2      y = 3x + 21

2.- Solve the system by equality

                      5x + 3 = 3x + 21

                       5x - 3x = 21 - 3

                               2x = 18

                                 x = 18/2

                                 x = 9

3.- Find the total number of chairs

y = 5(9)+ 3                         y = 3(9) + 21

y = 45 + 3                          y = 27 + 21

y = 48                                y = 48

4.- Conclusion

There are 48 chairs
