Answer: Hello there!
We want to find a counterexample to: "a square has four right angles" then we need to find a figure that has four right angles and is not a square.
A first example can be a cross (two segments that cut each other and are perpendicular), but let's think in a geometric shape.
Think on a square that in the middle of each side has a small semicircle; this shape still has four right angles but is not more a square.
There you have two counterexamples of the definition given.
a flat figure with 4 equal straight sides and four right angles

Answer:
7/3
Step-by-step explanation:
f(x) =7/(x+2)
g(x) = (x + 5)^2
f(g(-4))=
First find g(-4)
g(-4) = (-4+5)^2
=(1)^2 =1
Then find f(1)
f(1)= 7/(1+2)
= 7/3
There are 7 keys in each octave (C,D,E,F,G,A and B) so it would make sense to divide 52 to 7.
52/7=7 octaves and 3 extra kets
A. 1/5
A.
14
15
are the right i think
