Why is it important to reduce radicals

Answers

Answer 1
Simplifying radical expressions expression is important before addition or subtraction because it you need to which like terms can be added or subtracted. If we hadn't simplified the radical expressions, we would not have come to this solution. In a way, this is similar to what would be done for polynomial expression.

How do you know each of the sides of the shape are the same length?

Answers

Answer:

If your shape is a regular polygon (such as a square in the example above) then it is only necessary to measure one side as, by definition, the other sides of a regular polygon are the same length. It is common to use tick marks to show that all sides are an equal length.

Last month Maria hiked a total of 90 miles on two trails: a 5-mile mountain trail and a 10-mile canal trail. Let x represent the number of times Maria hiked the mountain trail, and let y represent the number of times Maria hiked the canal trail.

Which equation can be used to find the number of times Maria hiked each trail?

Answers

The relation is 5x+10y=90
Because If she hiked the 5-mile trail x times, she would have walked 5x miles in total.
Likewise, if she hiked the 10-mile trail y times, she would have walked 10y miles as she did so. Since we know the total of her walking was 90 miles, we can write the above equation, linking together the information.
Without additional information about x and y (such as being told she went hiking 12 times in all, for example) we cannot come to a definite statement about the values of x and y

a father is 25 years older than his son.Five years ago he was 6 time old as his son was find their presents

Answers

Answer:

the present age of the father be x and the present age of the son be y.

It is given that man is 24 years older than his son that is:

x=y+24

x−y=24..........(1)

Also, 12 years ago, he was five times as old as his son that is:

(x−12)=5(y−12)

x−12=5y−60

x−5y=−60+12

x−5y=−48..........(2)

Now subtract equation 1 from equation 2 to eliminate x, because the coefficients of x are same. So, we get

(x−x)+(−5y+y)=−24−48

i.e. −4y=−72

i.e. y=18

Substituting this value of y in (1), we get

x−18=24

i.e. x=24+18=42

Hence, the present age of the father is 42 years and the present age of the son is 18 years.

The midpoint of UV is (5, -11). The coordinates of one endpoint are U(3,5). Find the coordinates of endpoint V.

Answers

The coordinates of endpoint V is (7, -27) if one endpoint is U(3,5) and the midpoint of UV is (5, -11)

Midpoint of a line is a point that divides any line into two equal parts.

The midpoint of two coordinates (x1, y1) and (x2, y2) is expressed as:

[tex]M(X, Y)= (\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2} )[/tex]

Given the following

midpoint of UV = (5, -11)

U = (3, 5)

Get the other coordinate x2 and y2

Based on the formula above:

[tex]X = \frac{x_1+x_2}{2}\\5=\frac{3+x_2}{2}\\10 = 3 + x_2\\x_2 = 10-3\\x_2 = 7[/tex]

Get the other coordinate x2

[tex]Y = \frac{y_1+y_2}{2}\\-11=\frac{5+y_2}{2}\\-22 = 5 + y_2\\y_2 = -22-5\\y_2 = -27[/tex]

This shows that the coordinates of endpoint V is (7, -27)

Step-by-step explanation:

The nth term of an arithmetic sequence is

where a₁ is the first term and d the common difference

Given a₉ = 16 , then

Step-by-step explanation:

Allow me to revise your question for a better understanding and I hope it will fit the original one.  

The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.

Here is my answer:

Given:

The area: 72 units squared.

The base: 6 units

As we know that the area of the parallelogram is represented by below formula:

A = b*h where h is the height and b is the base

In this situation, we know:

72 = 6*h

<=> h = 12

So the missing height is 12 units

Hi there!

Angles in a triangle sum up to 180°, so:

180° = 110° + 5x° + 2x°

Simplify:

180° = 110° + 7x°

Subtract both sides by 110:

70° = 7x°

Divide both sides by 7:

x = 10°

Plug in to solve for the other angles:

5x = 5(10) = 50°

2x = 2(2) = 20°

110 + 2x + 5x = 180
110-110+7x=180-110
7x=70
7x/7= 70/7
x=10

To find the distance between 2 points, we want to use the formula [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given the 2 points, all we have to do is plug them in.
