The correct answer is D, since a rotation of 360 has no effect, since the figure does a whole turn and returns where it was.
Because the problem stated that "the rancher plans to use 100 feet of fencing", we know that all of the sides of the fence must add up to 100 ft. Using this information, you set up an equation.
100=x+x+(x+4)+(x-3)+5 Then you combine like terms:
100=4x+6 Subtract 6 from both sides:
94=4x Divide both sides by 4:
23.5=x
Therefore, x=23.5 ft.
Answer:
140.63 is the correct answer
Step-by-step explanation:
Since we have given that
Length of 1 square tile = 11.25 inches
Number of tiles to cover the length of floor = 12.5
We need to find the length of the floor.
So, Length of floor is given by
Length of 1 square tile × Number of tiles
Hence, the length of floor is 140.625 inches.

Explanation</h2>
⇒ First, factor the numerator by grouping:
⇒ Now, factor the denominator by grouping:
⇒ We must determine which values of <em>e</em> and <em>f</em> are unacceptable, meaning, will make this expression undefined. These will be the values of <em>e</em> and <em>f</em> that make the denominator equal to 0.
- ⇒ To find these values, let's set each term in the denominator equal to 0, and solve for <em>e</em> and <em>f</em>.
- ⇒ ⇒
- ⇒
- ⇒ The restrictions for <em>e</em> and <em>f</em> include and .
⇒ Reduce values in the numerator and denominator:
