Consider this quadratic equation. 2x2 − 1 = 3x + 4 Which equation correctly applies the quadratic formula?

Mariulka [41]

Answer:

$\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)}$

Step-by-step explanation:

Quadratic formula: $\frac{-b+-\sqrt{b^2-4ac} }{2a}$

$2x^2-1=3x+4\\\\2x^2-3x-5=0\\\\\\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)} \\\frac{3+-\sqrt{9+40} }{4}$

$x = \frac{3+-7}{4}$

Hope this helps and God bless!

Eileen’s cookies charges $0.40 per cookie with a delivery fee of $8. Insomnia cookies charges $1.50 per cookie with a $2.50 deli

Nuetrik [128]

Answer: 5 cookies

Step-by-step explanation: 8 + .4c = 2.5 + 1.5c

8 + 0.4c = 2.5 + 1.5c

8 · 10 + 0.4c · 10 = 2.5 · 10 + 1.5c · 10

80 + 4c = 25 + 15c

4c = 15c - 55

4c - 15c = 15c - 55 - 15c

-11c = -55

c = 5

Two angles of a Triangle measure 55° and 22° What is the measure of the third angle of the triangle

IgorC [24]

Answer:

c would be the closest

Step-by-step explanation:

All triangles equal 180*. so if you combine the 2 angles, which adds up to 77* then that would leave the third angle to be 103* but since that isnt an option choose c since its the closest.

Simplify completely the quantity 4 times x to the third power plus 5 times x to the 2nd power plus 3 times x all over x. (2 poin

julia-pushkina [17]

We start with

$\dfrac{4x^3+5x^2+3x}{x}$

We can factor x at the numerator:

$\dfrac{x(4x^2+5x+3)}{x}$

So, assuming $x\neq 0$ (otherwise the expression would make no sense) we can simplify it:

$\dfrac{x(4x^2+5x+3)}{x} = 4x^2+5x+3$

This equation has no roots, so we can't simplify it any further.
