[tex] \tt{(3 {a}^{2} + 2ab + 2b) + (5 {a}^{2} - 3ab + 9})[/tex]

~While adding , the sign of each term of second expression remains same. So, Remove the unnecessary parentheses :

⤑ [tex] \tt{3 {a}^{2} + 2ab + 2b + 5 {a}^{2} - 3ab + 9}[/tex]

~Like terms are those which have the same base. Combine the like terms :

⤑ [tex] \tt{3 {a}^{2} + 5 {a}^{2} + 2ab - 3ab + 2b + 9}[/tex]

⤑ [tex] \sf{8 {a}^{2} - ab + 2b + 9}[/tex]

[tex] \red{ \boxed{ \boxed{ \tt{ ⟿ Our \: final \: answer : 8 {a}^{2} - ab + 2b + 9}}}}[/tex]

Answer:

Simplified answer is: [tex]8a^2 - ab + 2b + 9[/tex]

Step-by-step explanation:

Key skills needed for understanding: Combining Like Terms

1) You are given the equation: [tex](3a^{2} + 2ab + 2b) + (5a^{2} - 3ab + 9)[/tex]

- Since you are adding here, you can remove the parentheses.

- If you remove them it would be --> [tex]3a^2 + 2ab + 2b + 5a^2 - 3ab + 9[/tex]

2) Now we have to combine like terms in order to simplify this equation.

Combining like terms is simply combining terms with the same base (such as the terms that have "ab" or the terms that have "[tex]a^2[/tex]" or the terms that have nothing  - these terms are numbers such as 9 or 5).

You can combine 2ab and -3ab, but you cannot combine 9 and 2b. Hope you understood this concept.

3) If you combine like terms ( [tex]3a^2 + 5a^2[/tex], [tex]2ab - 3ab[/tex]) you will get a different expression: [tex]8a^2 - ab + 2b + 9[/tex].

[tex]8a^2 - ab + 2b + 9[/tex] is the answer.

Hope you understood and have a nice day!! :D

Answer:

r = 20

Explanation:

-4 = r/20 - 5

-4 = r/20 - 5

-4 = 1/20r + -5

-4 = 1/20r - 5

1/20r - 5 = -4

1/20r - 5 + 5 = -4 + 5

1/20r = 1

(20)1/20r = 1(20)

A. What is the total amount to be paid at the time of the purchase?

This will be the selling price of the stereo with the tax and the deferral. This will be:

= $1052.75 + $40

= $1092.75

B) What is the amount of each monthly payment?

Each monthly payment will be gotten by dividing the total payment to be made by 12. This will be:

= $1092.75 / 12

= $91.06

Answer:

x = 31

Step-by-step explanation:

Given:

MN = 20

PQ = x

RS = 42

Required:

Value of x

SOLUTION:

In a trapezoid, the midsegment length equals the sum of both bases divided by 2

This implies that:

PQ = ½(MN + RS)

Plug in the values

x = ½(20 + 42)

x = ½(62)

x = 31

Answer:

Answer:

117°

Step-by-step explanation:

Angle of straight line is 180°

Angles in a triangle add up to 180°

starting at right

180 - 101 = 79° at right side angle in triangle

now solving left side angle

180 - 38 - 79 = 63°

now solving x using left side angle, must add to 180°

x + 63 = 180°

x = 117°

x is an exterior angle of the triangle and its measure is 117 degrees.

Given,

Triangle with interior and exterior angles.

Linear pair : ∠x + ∠y = 180 degrees.

Angle of straight line is 180°(Linear pair).

180 - 101 = 79°

Angle sum property: Sum of all the angles in a triangle add up to 180° .

So,

180 - 38 - 79 = 63°

Now solving x,

Angles must add to 180° in a straight line.

x + 63 = 180°

x = 117°

Therefore measure of angle x in the triangle is 117 degrees.

The percentage of students who scored above 520 is 0.13%.

Given data:

To determine the approximate percentage of students who scored above 520, use the concept of standard deviations.

Given that the mean score is 400 and the standard deviation is 40, calculate the z-score for the value of 520 using the formula:

z = (x - mean) / standard deviation

where x is the value of interest.

So, x = 520, mean = 400, and standard deviation = 40. Plugging in these values:

z = (520 - 400) / 40

z = 120 / 40

z = 3

The z-score of 3 represents a value that is 3 standard deviations above the mean.

To find the approximate percentage of students above 520, we can refer to the standard normal distribution table (also known as the Z-table). Looking up the z-score of 3 in the table, the area to the left of this z-score is approximately 0.9987.

To find the percentage above 520, subtract this value from 1 to find the area to the right of the z-score:

1 - 0.9987 = 0.0013

Hence, approximately 0.13% of students scored above 520 in the test.

Answer:

30% probability that the ball taken from B is red.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Red ball from urn A:

3/6 = 1/2 probability of getting a red ball from urn A.

Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.

Blue ball from urn A:

3/6 = 1/2 probability of getting a blue ball from urn A.

Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.

Total:

[tex]p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}[/tex]

3/10 = 0.3 = 30%.

30% probability that the ball taken from B is red.

area is measured in square units not perimeter

The perimeter does not measures in square units because area should be measured.

A perimeter refers to the closed path that encompasses or outlines and represents the two-dimensional shape or a one-dimensional length. The perimeter of a circle is known its circumference.

Unit vector along the direction v = <3,1,-4> is :

[tex]\hat{v} = \dfrac{3i + j -4k}{\sqrt{3^2 + 1^2 + 4^2}}\\\\\hat{v} = \dfrac{3i + j -4k}{5.1}[/tex]

So, unit vector opposing the [tex]\hat{v}[/tex] is :

[tex]\hat{v'} = -\hat{v}\\\\\hat{v'} = -( \dfrac{3i + j -4k}{5.1})\\\\\hat{v'} = \dfrac{-3i - j +4k}{5.1}[/tex]

so, vector of magnitude 3 units in opposite direction from v is :

Find out  the selling price.

To prove

As given

A store manager instructs his employees to mark up all the items by 25%. An item that the store bought for $16.

25% is written in the decimal form.

= 0.25

25% of the $16= 0.25 × 16

                         = $4

Selling price of the item = Original price of item + 25% of the $16

                                       = $16 + $4

                                      = $ 20

Therefore the selling price of the item is $20.
