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!

Step-by-step explanation:
I'm pre sure u divide the total number to make a 3 digit im not too.
but good luck :)
Answer:
B.
Step-by-step explanation:
The function is positive when it is above the x-axis
The following x values are where the function has positive y coordinates:
(-2,0)
(4,inf)
The function is negative when it is below the x-axis
The following x values are where the function has negative y coordinates:
(-inf,-2)
(0,4)
So you should see all of these intervals listed in choice B
Answer:
x=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
4x+x+3=18
(4x+x)+(3)=18(Combine Like Terms)
5x+3=18
5x+3=18
Step 2: Subtract 3 from both sides.
5x+3−3=18−3
5x=15
Step 3: Divide both sides by 5.
5x/5 = 15/5
x=3
