20 maybe
Step-by-step explanation:
i don't know what the other side of the polygon is
Answer: x=9 is an extraneous solution
Step-by-step explanation:
Given
Function is 
for function to exist
Therefore, 9 satisfies the above equation. It is it's extraneous solution.
C. the values can be added after making a conversion of units because they both measure length.
Answer: The hypotenuse is about 11 inches and it is greater than the legs
Step-by-step explanation:
Hi, we have to apply the Pythagorean Theorem:
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the legs.
Replacing with the values given:
c^2 = 7^2 + 9^2
c^2 = 49+81
c^2 = 130
c = √130
c = 11.40 inches
The hypotenuse is about 11 inches and it is greater than the legs
11.40>7 ; 11.40 >9
