Evaluate<br> 8.2+(3+0<br> ——<br> 3
jenyasd209 [6]

Answer:

11.2

Step-by-step explanation:

well i'm guessing that you didn't finish you parenthesis and if you did they would be around the 0 and 3 so 3 plus 0 is 3 and 3 plus 8.2 is 11.2 so I believe your answer is 11.2.  Sorry if it is wrong the question didn't really make sense.

Help I’ll give you 30 points
Gnesinka [82]

Answer:

a) 16.25 centimeters

b) 6.8 centimeters

Step-by-step explanation:

We can set up a proportion for both of these problems.

a) Look at the longest side of each triangle. We can set up a fraction: 7.2/18. We can also set up a fraction for XZ and PR:

6.5/x

x represents the length you're trying to find.

Since the triangles are similar, we have an equation:

7.2/18=6.5/x

Cross multiply

16.25

XZ is 16.25 centimeters long.

b)

We can do same thing:

7.2/18=x/17

Cross multiply

6.8

QR is 6.8 centimeters long.

Hope this helps!
