Make a conjecture about the product of an even and an odd number based on the following pattern: 2 = 2 x 1
6 = 3 x 2
30 = 5 x 6
56 = 7 x 8
90 = 9 x 10
and so on.
The product of an even and an odd number is equal to the square of the odd factor.
The product of an even and an odd number is an even number.
The product of an even and an odd number is equal to the sum of the factors.
The product of an even and an odd number is a prime number.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
