Answer:

The perimeter of triangle MNP is 130 units

Step-by-step explanation:

By the mid segment theorem, we have it that the a side of the smaller inner triangle is 1/2 the measure of the parallel side of the bigger triangle that faces it

This mean RS is half MN, QS is half NP and QR is half MP

Using this, we have it that;

2(x + 4) = 5x - 34

2x + 8 = 5x -34

5x-2x = 34 + 8

3x = 42

x = 42/3

x = 14

So we have RS which is x + 4 as 14 + 4 = 18

The perimeter of the smaller triangle is the sum of its side lengths

We have this as;

22 + 25 + 18 = 65

Furthermore, by the mid segment theorem , the perimeter of the bigger triangle is twice that of the smaller

thus, we have the perimeter of MNP as 2(65) = 130 units

-22 = 6x + 4<br> Hehehhe I need help agaaaaiiin

Hey there!

$Answer:\boxed{x=\frac{-13}{3}}$

$Explanation:$

$-22=6x+4$

Let's start off with flipping the equation.

$6x+4=-22$

Now we need to subtract 4 from both sides of the equation.

$6x+4-4=-22-4\\6x=-26$

Now in our third/last step, we will divide both sides by 6.

$\frac{6x}{6}=\frac{-26}{6}$

$x=\frac{-13}{3}$

$\boxed{x=\frac{-13}{3}}\text{ is the answer.}$

Hope this helps!

I need help with #10!

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

$x+3$

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

$x+3=\frac{3x}{2}$
