Round off then estimate 18.9*5.2

Use the discriminant to describe the roots of each equation. then select the best description. 2m2 + 3 = m double root real and rational roots real and irrational roots non-real roots

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 4x^2 - 19x- 5
