how do you solve a square root equation?​

Answer:

Step-by-step explanation:

4+6+10+10+15+17+19=81

Then you divide 81 by the numbers of the numbers given. Which is 7 numbers so it will be 81/7 which is 11.57 then you approximate it to 11.

Answer:  3. Distributive

Step-by-step explanation:

Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.

For example: a (b+c)= a b+ac  , where a,b,c can be any expression.

Given expression:  -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.

Hence, the correct option is 3. Distributive.

The rest of properties cannot work for multiplication over addition as they are used for one operation.

The third one is the right answer

Answer:

The first one is right. (A)

Step-by-step explanation:

Whenever we talk about compressions we just need to compress one of the axes in this case we are asked to compress the y-axis which means that the only values that will change are the y-values, don't get confused the x values have to stay the same.

Answer:

18

Step-by-step explanation:

The solution is Option B.

The value of the modulus function is A = 18

Regardless of the sign, a modulus function returns the magnitude of a number. The absolute value function is another name for it.

It always gives a non-negative value of any number or variable. Modulus function is denoted as y = |x| or f(x) = |x|, where f: R → (0,∞) and x ∈ R.

The value of the modulus function is always non-negative. If f(x) is a modulus function , then we have:

If x is positive, then f(x) = x

If x = 0, then f(x) = 0

If x < 0, then f(x) = -x

Given data ,

Let the modulus function be represented as A

Now , the value of A is

A = 6 | 5 - c | + 2c  be equation (1)

Now , when the value of c = 6

Substituting the value of c in the equation , we get

A = 6 | 5 - 6 | + 2 ( 6 )

A = 6 | -1 | + 2 ( 6 )

The value of the modulus function always returns a positive value ,

So , A = 6 ( 1 ) + 2 ( 6 )

A = 6 + 12

A = 18

Therefore , the value of A is 18

Hence , the modulus function is A = 18

Answer:

d. AB

e. A/B

Step-by-step explanation:

From the concept of homogeneity of dimension. The principle is that if two quantities occurs in the same direction, addition and subtraction of those two variable tends to occur but if two quantities occur in different direction, then we can only have either the division and multiplication of those quantities.

From the given information;

Suppose two quantities, A and B, have different dimensions.

Step-by-step explanation:

Given a ΔLMN.

Line LN is extended to point O.

such that:

[tex]\text{m}\angle MNO = (5x-13)^{\circ}[/tex]

[tex]\text{m}\angle NLM = (x-4)^{\circ}[/tex] and

To find:

[tex]\text{m}\angle NLM=?[/tex]

Solution:

Kindly refer to the attached image for the given triangle and dimensions of angles.

Let us recall the external angle property of a triangle:

The external angle of a triangle is equal to the sum of two opposite internal angles.

i.e.

[tex]\angle MNO = \angle NLM + \angle LMN\\\Rightarrow 5x-13 = x-4+2x+19\\\Rightarrow 5x-13 = 3x+15\\\Rightarrow 5x-3x = 13+15\\\Rightarrow 2x=28\\\Rightarrow x =14[/tex]

Answer:

4x + 16

Step-by-step explanation:

The area of the shaded region = area of the outer rectangle - area of the inner rectangle

Area of rectangle = l*w

Area of outer rectangle, where length (l) = (x + 5), and width (w) = (x + 4):

Area = (x + 5)(x + 4)

Expand

x(x + 4) +5(x + 4)

x² + 4x + 5x + 20

area of outer rectangle = x² + 9x + 20

Area of inner rectangle, where length (l) = (x + 4), and width (w) = (x + 1):

Area = (x + 4)(x + 1)

Expand

x(x + 1) +4(x + 1)

x² + x + 4x + 4

Area of inner rectangle = x² + 5x + 4

Area of shaded region = (x² + 9x + 20) - (x² + 5x + 4)

x² + 9x + 20 - x² - 5x - 4

Collect like terms together

x² - x² + 9x - 5x + 20 - 4

4x + 16

Area of the shaded region = 4x + 16

Answer: Answer is in the steps

Step-by-step explanation:

A)  First convert 65 miles to kilometers  

65 miles to kilometers  is 104.607  

Convert 1 hour to minute and that will be 60 minutes because 60 minutes makes and hour.

Now divide the kilometers by the number of minutes

104.607 / 60 = 1.74345  

The speed will be 1.74345 kilometers per minute.

B) Convert 3.5 hours to minutes.

3.5 hours is the same as 210 minutes    

Now multiply it by 1.74345 to determine how many kilometers you have traveled.

1.74345 * 210 = 366.1245

You will travel 366.1245 kilometers in 3.5 hours.

Step-by-step explanation:

Hey, there!

Here,

Given that:

[tex] = 25 {x}^{2} - 4[/tex]

we need to find factor,

As it is in a^2-b^2 form as per its factor (a+b) (a-b), keeping same formula here,

25x^2 means (5x)^2

and 4 means 2^2

Now, it would be,

[tex] = ( {5x)}^{2} - {2}^{2} [/tex]

[tex] = (5x + 2)(5x - 2)[/tex]

Therefore, it's factor would be (5x+2)(5x-2).

Answer:

y = 48 - (8x)

Step-by-step explanation:

x = unknown number of coworkers

y = number of chocolates left over

y = 48 - (8x)

Example: If you were to plug in the number 5 for x:

y = 48 - (8(5))

y = 48 - 40

y = 8

The answer is 48-8f
