What would be the answer to this ?
lyudmila [28]

The factorized form of the expression ( 2x² - x - 6 ) is ( 2x + 3 )( x - 2 ).

Hence, the missing values are 3 and 2 respectively.

<h3>What is the factorized form of the expression?</h3>

Given the expression: 2x² - x - 6

First, we factor -1 out of -x

2x² - x - 6

2x² -1(x) - 6

Not that, -1 can also be written as 3-4

2x² + (3-4)x - 6

2x² + 3x - 4x - 6

Next, we group the first two terms and the last two terms and factor out the GCF

(2x² + 3x) - 4x - 6

x(2x + 3) - 2( 2x + 3)

Factor out the GFC which is ( 2x+3 )

We have; ( 2x + 3 )( x - 2 )

The factorized form of the expression ( 2x² - x - 6 ) is ( 2x + 3 )( x - 2 ).

Hence, the missing values are 3 and 2 respectively.

Mr. Timmons wanted to fence in his rectangular back yard so that his son could play soccer. He bought 180 feet of fencing, which
elixir [45]

Answer:

The length of the yard is 60 feet while the width is 30 feet.

Step-by-step explanation:

If the length of Mr. Timmon's backyard is double the width, then the dimensions are related by the following expression:

length = 2*width

We also know the perimetter, since he has the exact length of fence to surround his whole yard, which is 180 feet. The perimeter of a rectangle is given by:

perimeter = 2*length + 2*width

Therefore,

180 = 2*length + 2*width

With the length being double the width, we have:

180 = 2*(2*width) + 2*width

180 = 4*width + 2*width

6*width = 180

width = 180/6 = 30

length = 2*width = 2*30 = 60

The length of the yard is 60 feet while the width is 30 feet.

Find m∠H What does m∠H happened to equal​
Tom [10]

Answer:

30 degrees

Step-by-step explanation:

The things we do have and want to find are as follows:

- We know that this is a right triangle, and one angle is 90 degrees

- We want to find an angle

- Relative to that angle, we are given an adjacent side as well as the hypotenuse

One equation that encompasses this is cos(θ) = adjacent/hypotenuse, so

cos(m∠H) = 10√3 /  20

For an equation of form cos(x) = y, we can say that arccos(y) = x. Therefore, we can write our equation as

m∠H = arccos(10√3 /  20)

m∠H = 30 degrees
