No, this is not a right triangle
Step-by-step explanation:
Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
Answer:
y should equal -25 if i did the math right
Step-by-step explanation:
-12 and 9 have a difference of -21 so if i subtract -21 from -4 it would equal -25.. hope this helps!!
3.482 x 10^9.
-the coefficient must be under 10, and in this case it is the "3". Then you count the places after that to get your exponent
