the function f(x)=6x+20 models the height of newborn, in inches, for the first four years of life. What does the x stand for? What does the coefficient of x mean? What does the constant tell us?

Which composition of similarity transformations maps polygon abcd to polygon a'b'c'd'? a dilation with a scale factor less than 1 and then a reflection a dilation with a scale factor less than 1 and then a translation a dilation with a scale factor greater than 1 and then a reflection a dilation with a scale factor greater than 1 and then a translation

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 20 = x a. 5, 4 b. -5, -4 c. -5, 4 d. 5, -4

∆red ≅ ∆ by rule will give brainiest if possible
