Find the value of L. Perimeter = 20. Width is 6. So what is L? On a square

Well first of all, that's not a square.  On a square, all 4 sides are
the same, and the length is the same distance as the width.  If the
width of a square is 6, and all four sides are the same, then the
perimeter is (4 x 6) = 24. 

So the shape in your question may be a rectangle, but it's definitely
not a square one.

The perimeter is the distance an ant has to walk if you put him down
on one corner and he walks all the way around the shape until he gets
back to where he started from. 
That's the perimeter.

If you set the ant down on the corner of a rectangle, then he walks the
length, then the width, the the length again, then the width again, and
he's back where he started.

That was 2 lengths and 2 widths ... the perimeter of every rectangle.

Take 2 widths away from the perimeter, and you have 2 lengths left.  OK ?

You said that the width of your rectangle is 6.  Two widths is 12.
Take the 2 widths away from the perimeter, and you're left with (20 - 12) = 8.
But that's 2 lengths !
So the length is half of 8  =  4 .

ASAP what is the value of k?<br> -3(k+7) - 5k+4=23
Maru [420]

Answer:

k=−5

Step-by-step explanation:

−3(k+7)−5k+4=23

(−3)(k)+(−3)(7)+−5k+4=23(Distribute)

−3k+−21+−5k+4=23

(−3k+−5k)+(−21+4)=23(Combine Like Terms)

−8k+−17=23

−8k−17=23

Step 2: Add 17 to both sides.

−8k−17+17=23+17

−8k=40

Step 3: Divide both sides by -8.

−8k

−8

=

40

−8

k=−5

Answer:

k=−5

Your surf shop sells two types of surfboards. The first type A, costs $272 and you make a profit of $29 on each one. The second
brilliants [131]
Let the number of type A surfboards to be ordered be x and the number of type B surfboards be y, then we have

Minimize: C = 272x + 136y

subject to: 29x + 17y ≥ 1210
                 x + y ≤ 50
                 x, y ≥ 1

From the graph of the constraints, we have that the corner points are:

(20, 30), (41.138, 1) and (49, 1)

Applying the corner poits to the objective function, we have

For (20, 30): C = 272(20) + 136(30) = 5440 + 4080 = $9,520
For (41.138, 1): C = 272(41.138) + 136 = 11189.54 + 136 = $11,325.54
For (49, 1): C = 272(49) + 136 = 13328 + 136 = $13,464

Therefore, for minimum cost, 20 type A surfboards and 30 type B surfboards should be ordered.
