Matlab a farmer wishes to build a rectangular pen for his animals out of 40 feet of fencing what should be the length and width

ASHA 777 [7]

Width=w
length=(40-2w)/2=20-w
A=w(40-w)
A=40w-w²
A'=40-2w=0
2w=40
w=20

20x20 is the size of the pen having the greatest area. this tells us the largest rectangle for a given perimeter is a square

Answer:

$\huge\boxed{\sf 3(n + 5) \leq 100}$

Step-by-step explanation:

The sum of a number n and 5 => n + 5

Thrice the sum of a number n and 5 => 3(n + 5)
At most means "less than or equal to", the sign of which is "≤"

<u>So, the inequality will be:</u>

3(n + 5) ≤ 100

$\rule[225]{225}{2}$

Hope this helped!

Parallel, intersecting or skew?

const2013 [10]

Two lines are:

Parallel if they don't intersect and lie on the same plane
Intersecting if...well, they intersect at one point
Skew if they don't intersect and they lie on two different planes

So, we have:

AB and BC intersect at point B
AE and BF don't intersect, but both lie on the plane AEFB
EF and AD don't intersect and don't lie on a common plane
ABC and ABF intersect on segment AB
AED and BFC are parallel (they're both perpendicular to plane ABC)
