Answer:
No because 16+49 does not equal 121.
Step-by-step explanation:
first make 11 the hypotenuse and 4 and 7 side b and A
Use the pythagorean theorem: A^2+B^2=C^2
4^2+7^2=11^2
16+49=121
Ask your teacher that’s all you have to do.
(x + 7)/2 - (x + 4)/2 = (x + 7 - (x + 4)/2 = (x + 7 - x - 4)/2 = 3/2
