The least number of computers that must be shipped is 10.
<h3>What is the least number of computers that must be shipped?</h3>
In order to determine the least number of computers that must be shipped, the equation that represents the cost of shipping should be equal to the selling price of the computers.
3000 + 100x = 400x
In order to determine the value of x, take the following steps:
3000 = 400x - 100x
3000 = 300x
x = 3000 / 300
x = 10

Answer:
product of the roots= c/a
Step-by-step explanation:
The the two roots(α and β) of the quadratic equation ax²+bx+c=0 as given by shridharacharya formula are
![\alpha= \frac{-b+\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Calpha%3D%20%5Cfrac%7B-b%2B%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
![\beta= \frac{-b-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cbeta%3D%20%5Cfrac%7B-b-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
now product of the roots
αβ=
×![\frac{-b-\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=%5Cfrac%7B-b-%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
use formula (a+b)(a-b)= a^2-b^2 and solve we get
αβ= c/a
therefore product of the roots= c/a
Answer: 45
<u>Step-by-step explanation:</u>
5 : 5 : 3 is simplified so it can be rewritten as 5x : 5x : 3x

Sara has 18 more than June --> 5x = 3x + 18
2x = 18
x = 9
In expanded form we have 5(9) : 5(9) : 3(9)
45 : 45 : 27
