$\\ \sf\longmapsto x+5+x-5=80$

$\\ \sf\longmapsto 2x=80$

$\\ \sf\longmapsto x=40$

Angles are

180-80=100°
x+5=40+5=45°
x-5=40-5=35°

What is the discriminant D of the equation? a2−2a+5=0 Enter your answer in the box.

xxMikexx [17]

For a quadratic equation ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac
Thus for a^2 - 2a + 5 = 0,
a = 1, b = -2 and c = 5
b^2 - 4ac = (-2)^2 - 4(1)(5) = 4 - 20 = -16

Which of the following is equivalent to the expression (9x^2y^3)(12x^-3y^5)(2xy)?

VladimirAG [237]

Answer:

$\large\boxed{(9x^2y^3)(12x^{-3}y^5)(2xy)=216y^9}\to\boxed{B.}$

Step-by-step explanation:

$(9x^2y^3)(12x^{-3}y^5)(2xy)=(9\cdot12\cdot2)(x^2x^{-3}x)(y^3y^5y)\\\\\text{Use}\ a^n\cdot a^m=a^{n+m}\\\\=216x^{2+(-3)+1}y^{3+5+1}=216x^0y^9\\\\\text{Use}\ a^0=1\ \text{for any value of}\ a\ \text{except 0}\\\\=216y^9$
