Answer:
A perfect square is a whole number that is the square of another whole number.
n*n = N
where n and N are whole numbers.
Now, "a perfect square ends with the same two digits".
This can be really trivial.
For example, if we take the number 10, and we square it, we will have:
10*10 = 100
The last two digits of 100 are zeros, so it ends with the same two digits.
Now, if now we take:
100*100 = 10,000
10,000 is also a perfect square, and the two last digits are zeros again.
So we can see a pattern here, we can go forever with this:
1,000^2 = 1,000,000
10,000^2 = 100,000,000
etc...
So we can find infinite perfect squares that end with the same two digits.

Answer: 12 weeks
Step-by-step explanation: you multiply 25x 12+75 so it’s 12 weeks
A rational number can be made into a fraction
0.21 = 21/100....so it is rational
Answer: 50
Find the area of the triangles then multiply by 2.
1/2 x 5 x 10 = 25
25 x 2 = 50
