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

PLS HELP WILL MARK U BRAINLIEST!! NO FAKE ANSWERS
erica [24]

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}

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)
