Since we know the polygons are similar, the side length ratio of each side must be equal.
13/5 = x/10
Multiply both sides by 10
x = 26
That's your answer. Have a nice day! :)
Answer:
A) 8
Step-by-step explanation:
The average of two numbers is 7.
6 and x have an average of 7.

(6 + x)/2 = 7
6+x = 14
x = 8
The number is 8.
Answer:
E) Line 5
Step-by-step explanation:
Line 5 contains the first incorrect mathematical process
Process
x−5(x+1)>3x+2
−4x−5>3x+2
−7x−5>2
−7x>7
x<−1
2/5 , i dont have an explanation but maybe try that! I just did the math on paper
The answer would be b
hope this helps.
