Using the fact that the triangles shown are similar, we can set up a proportion between the lengths of the sides. 

The side length in question is QR, or "x". To find its corresponding side in the larger triangle let's look at the similarity.

MNO is similar to PQR
Vertices are always written in order of correspondence when stating similarities. Since QR are the last two letters of the triangle's name, and NO are the last two letters of the larger triangle's name, we know that QR and NO are corresponding sides. We can apply this same method to any other side.

NO/QR = MN/PQ
(MN and PQ are also corresponding sides)
Now we can substitute the side names with their values.
4.5/x = 5/2
Cross multiply
5x = 9
Divide both sides by 5
x = 9/5 or 1.8 or 1 4/5

Hope this helps!

Hello!

ΔMNO ≈ ΔPQR

MN ≈ PQ

MN = 5
PQ = 2

NO = QR

4 1/2 = 9/2

\frac{2}{5} \times  \frac{9}{2} =  \frac{18}{10} = 1  \frac{8}{10} = 1  \frac{4}{5}

Answer ⇒ 3rd choice

5 squares are placed end to end as below (see pic). What is the perimeter of the rectangle formed by the squares?
Nataly_w [17]
2b: If x is 2.1, then one side of the rectangle is 2.1, and another is 2.1*5=10.5.  Thus, the perimeter is 2*(2.1+10.5)=2*12.6=25.2.

3: One side of the square with side-length three will not be on the outside, so we have 3*3=9 inches perimeter from the square of side-length 3.  The square of side-length 6 has 3 from the top side missing from the outer perimeter, because it coincides with a side of the square of side-length three.  This square contributes 6*4-3=33 inches.  The total perimeter is 33+9=42 inches.

Complete the process of solving the equation. Fill in all missing terms and select all missing descriptions. Simplify any fracti
Sati [7]

Answer:

Step-by-step explanation:

WE willl solve the question for the following equation -8c-10+4c=-6c+8

1. Add 8c on both sides

8c-8c-10+4c = 8c-6c+8

-10+4c = 2c+8

2. Add 10 on both sides

10-10+4c = 10+2c+8

4c = 2c+18

3. Substract 2c on both sides

4c-2c = 2c+18-2c

2c =18

4. Divide both sides by 2

\frac{2c}{2}=\frac{18}{2}

c=2

Then, the equation is solved.
