Correct answer:
"<span>If the sum of the squares of the two shorter sides equals the square of the longest side, then the triangle is a right triangle"
the Pythagorean theorem states that in a right triangle, the sum of the squares of the shortest sides is equal to the square of the largest side, the hypotenuse.
Also,
If we have a triangle with side lengths a, b and c, where a and b are the shortest, and "a squared plus b squared = c squared" then the triangle is a right triangle.

Answer:
The third, they are equivalent because the size of the shaded area is the same.
I think x = -12 , if that’s what the questions asking
Answer:

Step-by-step explanation:

Add 6 to both sides:


Divide both sides by -3:


Subtract 4 from both sides:


Divide both sides by 2:


Due the parentheses first so 16+4+11*2-21 then multiply 16+4+22-21 from here you can answer left to right 20+4+22-21 then 24+1=25
