Aposter is to have an area of 180 in2 with 1 inch margins at the bottom and sides and a 2 inch margin at the top. find the exact dimensions that will give the largest printed area.

x = 2√30

y= 3√30

Step-by-step explanation:

Area= 180in^2

For the larger shape,

Let the length be x and the width be y

A = x. y

x. y = =180

y= 180/x

For the smaller shape, lenght= x-2 while width = y-3

Area = (x-2)(y-3)

A(x) = (x-2)(y-3)

Put y= 180/x into A(x)

= (x-2)(180/x -3)

= 180 - 3x - 360/x + 6

Differentiate A(x) with respect to x

A'(x) = -3x+ 360/x^2

A'(x) = 0

0 = -3x + 360/x^2

3x = 360/x^2

3x^3 = 360

x^3 = 360/3

x^3 = 120

x = cuberoot 120

x = 2√30

Recall that y= 180/x

y = 180/2√30

y= 90/√30

By rationalizing the surd, we have

y = 90/√30 * √30/√30

y = (90√30) /30

y = 3√30

x = 2√30, y = 3√30

javeir earned 56 dollors more than kyle so kyle and javier had 14w but javier made 56 dollors more so 14w plus 56 equals 70w so kyle has 14w

step-by-step explanation: hope i plz give me brainliest with the points so this is not constant cause it says last week so its clearly not every week

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14

and that lightbulb changing party must be freaking lit!
