The answer is 7/20. 1/4= 5/20 and 3/5 = 12/20
What I did was find the GCF (greatest common factor) of both 4 and 5 which was 20. Then I multiplied both numerators by the same number I multiplied the denominator with. Afterwards I subtracted both numerators (12-5) and this equals to 7
Hope that helps

Answer:
4 is not the constant. 2 is.
Step-by-step explanation:
In the following equation: y = 4x + 2
x and y are variables. x can be any given number, and y would be the resulting answer.
4 is not the constant, because the product it will produce varies on what x will be.
2 is a constant, because it will not change regardless what is put into x. It will continue to stay as 2.
Answer:
512
Step-by-step explanation:
the number of subsets of the set {1, 2, 3, ..., 9} is : 2^9 = 512
The expansion of a perfect square is
In words, the square of a sum of two terms is the sum of the squares of the two terms (
and 
), plus twice the product of the two terms (
)
So, when determining if you have a perfect square trinomial, you should have two perfect squares. Note that they don't have to be the first and third term, since you can rearrange terms as you prefer.
