Answer:
-8/9 or -0.8 repeating
Step-by-step explanation:
If this is a right triangle, then

where c is the hypotenuse which is ALWAYS THE LONGEST SIDE. Our longest side is 5, so we will set up Pythagorean's Theorem to see if the addition of the squares of a and b = the square of c:

. Squaring all of that and adding on the left gives us 25=25. Because this is true, we have proven the converse of the Pythagorean Theorem here and this is a right triangle.
The answer is b the median decreased and the median increased
Answer: 11x - y = 8x - y + 3x
Hi there,
Remove parenthesis,
7 + 9 + (-4)
Then, use the addition and subtraction rules:
7 + 9 - 4
Hence, the answer is 12 (C)
Hope this helps :)
