Simplify this expression
Thank you :)

Answer:

[tex] \boxed{ \bold{{ \boxed{ \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}}}}}[/tex]

Option A is the correct option.

Step-by-step explanation:

[tex] \sf{( {x}^{2} + 6x + 9)(3x - 1)}[/tex]

Use distributive property

⇒[tex]{ \sf{ {x}^{2} (3x - 1) + 6x(3x - 1) + 9(3x - 1)}}[/tex]

⇒[tex] \sf{3 {x}^{3} - {x}^{2} + 18 {x}^{2} - 6x + 27x - 9}[/tex]

Collect like terms

⇒[tex] \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}[/tex]

Hope I helped!

Best regards! :D

Answer:

3x^3 + 17x^2 + 21x - 9

Step-by-step explanation:

Use distributive property.

First distribute the 3x

3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x

Now we distribute the -1

-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9

We Add both answers-

  3x^3 + 18x^2 + 27x

+               -x^2     -6x - 9

Answer:

24 candy bars

Step-by-step explanation:

1case=6boxes of candy bars

1 case=144 candy bars

1 box has the same number of candy bars as the rest

What is the number of candy bars in 1 box

6 boxes = 144 candy bars

1 box = ?

144×1 ÷6= 24 candy bars

1 box has 24 candy bars

Answer:

15

Step-by-step explanation:

The ratio has been simplified so it may be hard to read.

To fix this multiply both the 5 and 7 by 3

This will give you 15:21

15 + 21 = 36 which is the total number of students.

Keeping the ratio in the same order means that there are 15 boys.

Answer:

There are 15 boys in the class.

Step-by-step explanation:

There are several ways to solve this, but here's how I did it:

5 (boys) : 7 (girls) = 12 students. There are 26 students, so we need to multiply this by 3.

15 (boys) : 21 (girls) = 36 students.

Answer:

90% percent of the computers are working.

Step-by-step explanation:

3/30 of the computers don't work and we can simplify this

1/10 or 10% Subtract 10% from 100%

90% are working computers.

Answer:

A.true

Step-by-step explanation:

The domain of a quadratic function in standard form is always all real numbers, meaning you can substitute any real number for x. The range of a function is the set of all real values of y that you can get by plugging real numbers into x.

Answer:

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side b

Using Pythagoras theorem we have

a² = b² + c²

where a is the hypotenuse

Substitute the values into the above formula and solve

That's

We have the final answer as

Hope this helps you

Answer:

35

Step-by-step explanation:

To solve for the hypotenuse of a right triangle, we use the Pythagorean Theorem, which is an equation to solve for the length of the hypotenuse given the two sides. The equation is a^2+b^2=c^2, where A and B are the legs of the triangle, and C is the hypotenuse. Let's manipulate this equation now. We are given one leg and the hypotenuse length, so the equation would be 12^2+b^2=37^2. Since we are trying to find the length of one of the legs, you subtract 12^2 from 37^2 to isolate B, and you get B^2 as 1225. You take the square root of both sides, and then you get 35 as the answer.

Answer:

430 + 16h

Step-by-step explanation:

They are staying for a week ($430)

They are renting both a kayak ($7 per hour) and paddle board ($9 per hour), without defining the amount of hours. Create a variable, for example H for hours.

To create the expression, take the $430, the $7 per hour and $9 per hour, or 430 + 16h.

Answer:

3.7×1.2=3+0.7+0.6+0.14=4.44

Step-by-step explanation:

I added all the choices together I picked the one that had the same answer. Good luck!

Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Given is that Owen creates this model to determine the product of two decimals.

The equation that represents the Owen's model is -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Therefore, Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44
