What equation is equivalent to x2 + 20x + 81 = -27? Can you show me how you got the answer please
Alla [95]

The equivalent equation is x² + 20x = -102

<h3>Simplification of quadratic equation</h3>

The equivalent equation can be obtained by factorizing or simplifying the given quadratic equation as shown below;

x² + 20x + 81 = -21

<em>collect similar terms together</em>

x² + 20x + 81 + 21 = 0

x² + 20x + 102 = 0

The equation can also be written as x² + 20x = -102

Thus, the equivalent equation is x² + 20x = -102

You are preparing a community garden with your youth group to have enough room for the spots for all the people who already sign
Annette [7]

Answer:

<u>92 feet.</u>

Step-by-step explanation:

Given:

The length of the garden needs to be 22 feet longer than the width of the garden.

The perimeter of the fence is a total of 324 feet

Question asked:

What will the length be of garden ?

Solution:

As length of the garden needs to be 22 feet longer than the width,

<u>Let width</u> = x

Then,<u> length </u>will be = x+22

As here perimeter of the fence is given, we can find length and width of garden by using:

Perimeter of rectangle = 2(length+width)

324=2(x+22+x)\\324=2(2x+22)\\324=4x+44\\

Subtracting both sides by 44

324-44=4x+44-44\\280=4x\\

Dividing both sides by 4

70=x

Width = x = 70 feet

Then, length will be = x+22 = 70 + 22 = 92 feet

Therefore, the length of the garden will be 92 feet.
