A perfect square is what u get when u multiply 2 of the same numbers together.
For example : 2 * 2 = 4.....4 is a perfect square
3 * 3 = 9...9 is a perfect square
4 * 4 = 16....16 is a perfect square
2 cannot be a perfect square because u cant multiply anything by itself that equals 2.
so ur perfect square numbers are : 1,4,9,25,36,81,144,225,400
9 x 7 is 63 and + 8 equals 71, when divided by 2, you get 35.5
35.5 is your answer
Answer: 5 + j/3
Step-by-step explanation:
Dividing the fare equally
Since they shared the j fare evenly among 3 people, you would divide the j fare by 3 to get j/3
So each person, including Angela, paid j/3 dollars before the tip
Adding the tip
Angela then added 5 dollars to this j/3 so the expression would become 5 + j/3
Final Answer
Angela paid $5 + j/3
By pythagoras theorem,
cb^2 = ac^2 + ab^2
5^2 = ac^2 + 3^2
ac^2 = 5^2 - 3^2 = 16
ac = squareroot 16 = 4cm
