Answer: It  can be calculated by using the formula of perimeter and by adding four sides

1) Perimeter= 2(L+B)= 8n+12

2) Perimeter= L+L+L+L= 4L= 8n+12

Step-by-step explanation:

As it is a square playground all its sides are equal

Perimeter of the sidewalk = 2(L+B)= 2(2n+3+0.5)= 2(2n+3.5)= 4n+7

Perimeter of the square playground= <em><u>2(L+B)</u></em>= 2(2n+3+2n+3)

<em>2(4n+6)= 8n+12-------------------------A</em>

Perimeter of the square playground<u><em>= L+L+L+L=4L</em></u>  42n+3+2n+3+2n+3+2n+3=<u><em>4(2n+3)= 8n+12------------------------B</em></u>

How do I graph this? Please use a picture

You first have to turn 2x + 4y = -8 into y = mx + b before graphing. To do this, you subtract 2x from the left side of the equation because inverse operations. This will bring 2x to the right side. Now, you will have 4 = -2x + 8. However, you cannot have a number with y. Therefore, you must divide -8 and 2 by 4. You will get y = -1/2 x + 2 as your equation. 
To graph -1/2x + 2, you must remember rise/run. Since it is NEGATIVE -1/2, your slope will go downwards (1 down, 2 across) starting from y = 2.

CAN YOU HELP ME PLEASEEEE ITS GEOMETRY!!! THANK YOUUU
valentinak56 [21]

Answer:

CE= 32

QS= 14

Step-by-step explanation:

Since the C=R and the E=Q, and the RQ is 16, the CE is 2x that value. (Since the CDE is 2x bigger than RSQ)

You also want to flip the triangles until they are in the same positions as each other so you can analyze it easier

Answer:

4

Step-by-step explanation:

if the area is 1/4 that would mean that the sides are equal to 1/2. if you stretch 1/2 out 4 times longer that would be equal to 2. 2 x 2 = 4
