Hello,

Let's be x the length of the 3 side (9,x,23) ==>x>0

Using inequality triangular:

9<x+23==>x>9-23==>x>-14 (done)
x<9+23==>x<32
23<x+9==>x>14

SO 14<x<32

Question 15

Viefleur [7K]

Answer:

0.71

Step-by-step explanation:

1st attempt = $\frac{14}{22} = 63%$ %

2nd attempt = $\frac{22}{28} = 79%$ %

To get the average of something, find the sum of the numbers and then divided the sum by the total number of values there are.

⇒ 63 + 79 = 142

⇒ 142 / 2 = 71%

⇒ 71% = .71
