What is the quotient?
Setler79 [48]

Answer:

Option 3) \frac{1}{(t+4)^{2}}

Step-by-step explanation:

In the given question we have to calculate the quotient after division.

To solve this question we will factorize (t²+7t+12) first and then we will will divide by this.

⇒ t²+7t+12 = ( t²+4t+3t+12)

⇒ t(t+4)+3(t+4)

⇒ (t+3)(t+4)

Now its a simpler form of divisor to get the answer.

We come back to the question

\frac{(t+3)}{t+4}\div(t^{2}+7t+12)

= \frac{(t+3)}{t+4}\div(t+3)(t+4)

Or =\frac{(t+3)}{t+4}\times\frac{1}{(t+3)(t+4)}

=\frac{1}{(t+4)^{2}}

So the right answer is \frac{1}{(t+4)^{2}}

Kelly has 236 feet of fence to use to enclose a rectangular space for her dog. She wants the width to be 23 feet. Select the cor
Setler [38]

Answer:

Length = x feet = 95 feet

Step-by-step explanation:

The labeled triangles are not included in the question, therefore, I will calculate the length of the rectangular space for Kelly's dog

Perimeter of a rectangle = 2(length + width)

Perimeter of a rectangle = 236 feet

Width = 23 feet

Length = x feet

Perimeter of a rectangle = 2(length + width)

236 = 2(x + 23)

236 = 2x + 46

236 - 46 = 2x

190 = 2x

x = 190/2

x = 95 feet

Length = x feet = 95 feet
