Can someone please help me with using the quadratic formula to find the solutions to the equation

galina1969 [7]

A quadratic equation has the standard form:

ax^2 + bx + c = 0

in the given equation,
a = 3
b = -10
c = 5

plug these values into the quadratic formula.

(-b +/- sqrt(b^2 - 4ac)) / (2a)

(-(-10) +/- sqrt((-10)^2 - 4(3)(5)) / (2*3)
(10 +/- sqrt(100 - 60)) / (6)
(10 +/- sqrt(40)) /6

The ratio of pens to pencils in the box is 84 to 112. Which statement describes this relationship?

Oksi-84 [34.3K]

Answer:

For every 84 pens there are 112 pencils in the box.

Step-by-step explanation:

We are given the following information in the question.

We are given a ratio of pens to pencil is 84 to 112.

Ratio is a relationship between two numbers that helps us to know how first number is related to the second number.

This can be written as: 84 : 112

This can be read as: For every 84 pens there are 112 pencils in the box.

Simplifying the fraction we have:

$\displaystyle\frac{84}{112} = \frac{21}{28}$

This ration can be written as 21 : 28 which means for every 21 pens in a box there are 28 pencils in the box.
