Answer:

<u>41 yards by 118 yards</u>

Step-by-step explanation:

Let W and L be the Width and Length of the playing field:

The perimeter, P, would be P = 2W + 2L

We are told that P = 318 yards.

We learn that L = 3W - 5

Combining this information, we can say:

P = 2W + 2L                         [Oriinal equation]

318 = 2W + 2L                      [P is 318]

318 = 2W + 2(3W-5)             [ Use the definition of L = 3W - 5]

318 = 2W + 6W - 10

328 = 8W

W = 41 yards

Use this value of W to find L:

L = 3W - 5

L = 3(41) - 5

L = 123 - 5

L = 118

<u>CHECK</u>

Does 2*(118) + 2*(41) = 318?  <u>YES</u>

Is the length 5 yards less than triple the width?

3*(41) - 5 = 118  <u>YES</u>

12 to the third over 12 to the seventh (12^3/12^7)? the answers are 12^4, 1/12^4, 1/12^-4, or 12^10
vaieri [72.5K]

12^3 / 12^7

Cancel out the common factor:

Multiply the numerator by 1:

12^3 * 1 / 12^7

Factor 12^3 out of the denominator to get:

12^3 * 1 / 12^3 * 12^4

Now cancel the common factor to get:

1/12^4
