FIND MEASURE OF ANGLE QRS!!

Xto the second power plus 14x plus 48. what are the factors? we are doing factoring trinomials with a=1

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

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
