Find the discriminant for this equation. x2 + 3x + 1 = 0

5

Step-by-step explanation:

if ax^2 +bx + c >discriminant formula is b^2 - 4ac  from the quadratic formula

x2 + 3x + 1 = 0

Then;

a=1

b=3

c=1

b^2 - 4ac = 3^2 -4*1*1

= 9-4

= 5

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
