-2x^4 + 14x^2 - 24

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

Will mark brainliest, , and rate to only chrislaurencelleenzo is making a scale drawing of the rectangle below. ~imageenzo says that he can draw an enlarged rectangle that is 16 centimeters by 13 centimeters. which explains whether enzo is correct? enzo is correct because he used a factor of 2 to enlarge the rectangle. enzo is correct because he doubled one dimension and added the two lengths to get the other dimension. enzo is not correct because the enlarged rectangle should be 16 centimeters by 5 centimeters. enzo is not correct because he did not multiply the length and width by the same factor.
