Answer:
Step-by-step explanation:
39²=1521
80²=6400
39²+80²=1521+6400=7921
87²=7569
7921≠7569
so it is not aright angled triangle.
7 + 14x means that a number x (x could be any real number) times 14 is added to 7.
So if x = 2:
7 + 14x = 7 + 14(2) = 28 + 7 = 35
Happy to help!
30. is just asking where the two equations graphed intersect each other...
x = -3 and x = 1 for intersections.
