Triangle squares and hexagons are the Only regular shapes which tessellate by themselves. You can have other tessellations of regular shapes if you use more than one type of shape. You can even tessellate pentagons, But they won’t be regular ones.

Would appreciate if given brainliest:)

find the dimensions of the sports field at the right if the width is at least 60 yards AREA = 240 - 400X SQUARE YARDS

Answer:

<u>The dimensions of the sports field are 80 yards and 3 - 5x yards</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Width of the sports field = At least 60 yards

Area of the sports field = 240 - 400x square yards

We can conclude the shape of the sports field is rectangular.

2. Find the dimensions of the sports field.

A. We need to find the Greatest Common factor between 240 and 400, this way:

The factors of 240 are: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240 .

The factors of 400 are: 1, 2, 4, 5, 8, 10, 16, 20, 25, 40, 50, 80, 100, 200, 400 .

Then the greatest common factor is 80.

This GCF is also higher than 60, therefore it's one of the dimensions of the sports field.

Now, we calculate the other side of the sports, this way:

Second dimension of the sports field = (240 - 400x)/80

Second dimension of the sports field = 3 -5x

<u>The dimensions of the sports field are 80 yards and 3 - 5x yards</u>

nadezda [96]

Answer:

a) v = 0

b) b = 7 / 6

c) a = any number

Step-by-step explanation:

a) 7(2+5v)=3v+14

7 x 2 + 7 x 5v = 3v + 14 .... distributive

14 + 35v = 3v + 14

35v - 3v = 14 - 14

32v = 0

v = 0 ...... only v value can fit

b) -3 (3-6b)=6b+5

-9 + 18b = 6b + 5

18b - 6b = 5 + 9

12b = 14

b = 14 / 12 = 7 / 6

c) 2 (a-2)=2a-4

2a - 4 = 2a - 4

2a -4 + 4 = 2a -4 + 4

2a = 2a

a = a ........ a cab be any number
