Find the expression that is equivalent to 7(x2 – 5x + 1). 9 x 2 +18 - 2 x 2 – 11 + 35 x 9 x 2 +18 - 2 x 2 – 11 – 35 x 9 x 2 + 8 - 2 x 2 – 11 – 35 x 9 x 2 +18 - x 2 – 11 – 35 x

Which of the following represents a number squared is equal to twenty more than nine times that number ? a) x squared = 9x + 20 b) x squared = 20x + 9 c) x squared > 9 + 20x d) x squared = 9 + x + 20

I'll give brainliest if you answer right : )
