Answer:

c  ≤ -14/17

Step-by-step explanation:

-32c+12 ≤-66c-16

-32c+12-12 ≤-66c-12-12

-32c ≤-66c-28

-32c+66c ≤-66c-28 +66c

34c ≤-28

34c/34 ≤-28/34

A triangle has side lengths of 10 inches, 24 inches, and 26 inches. is this a right triangle?

Answers

To check it we can use Pythagorean theorem.
a^2+b^2=c^2, where c is the longest side.
Lets check it
Assume that a=10 and b= 24
10^2+24^2=100+576=676
Now lets compare with c^2=676
Its equal, so its right triangle.
