simplify by using distributive property
3+11(2c+3)

Answers

Answer:

22c+36

Step-by-step explanation:

3+11(2c+3)

3+22c+33

3+33+22c

36+22c or 22c+26

Hey there!

In order to simplify this expression, all we have to do is distribute 11 by multiplying it times 2c and 3 and then combining like terms,

3+22c+33

As you can see, 3 and 33 are like terms; in order to simplify the expression, we should add them together.

36+22c

or

22c+36

Hope everything is clear.

Answers

Answer:

I didn’t really encounter any difficulty in determining a polynomial. The issue was that numbers with negative exponents or those which had square roots in them aren’t referred to as polynomials.

Answer:

The first one

Step-by-step explanation:

4x - 3y = 15  .first you subtract the 4x from both sides to get it in correct form

-3y = -4x + 15 . Then you divide both sides by -3 to isolate the y

y = 4/3x - 5  . Then you are left with this answer

Answer:

y = 4/3x - 5 (first answer on your photo)

Step-by-step explanation:

4x - 3y = 15

4x - 3y = 15 (we use -4x)

-3y = 15 - 4x (divide by -3)

y = 4/3x - 5

Given the relation y = –4x2 – 8, if the input is 2, what is the output?

Answers

Answer:

y = -24

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

y = -4x² - 8

x = 2

Step 2: Solve

Substitute:                   y = -4(2)² - 8Evaluate:                      y = -4(4) - 8Multiply:                       y = -16 - 8Subtract:                      y = -24

Answer:

Given, input (x) is 2,

[tex]y = -4x^2 - 8\\y = -4(2)^2 - 8\\y = -4(4) - 8\\y = -16 - 8\\y = -24[/tex]

Output (y) is 24

I need serous help like now Marie can find the volume of a cube by using the formula V = s³, where s represents the side length of the cube. If Marie's cube has a side length of 2 1\2 centimeters, what is the volume of her cube? Show your work. Make sure that you include the correct unit of measure in your answer.

Answers

Answer:

[tex]V=15.62\ cm^3[/tex]

Step-by-step explanation:

The volume of a cube is given by the formula :

V = s³, where s represents the side length of the cube

The side length of Marie's cube is [tex]2\dfrac{1}{2}\ cm[/tex]. We need to find the volume of her cube. For this, we can use the formula of the volume of a cube such that,

[tex]V=(2\dfrac{1}{2})^3\\\\=(\dfrac{5}{2})^3\ cm^3\\\\=\dfrac{125}{8}\ cm^3\\\\=15.62\ cm^3[/tex]

And the measure of angle BDA is 21 degrees

Step-by-step explanation:

Answer: ∠BDA = 21; CB = 30

have:

sin ∠BDC = [tex]\frac{4x+6}{BD}[/tex]

sin ∠ADB = [tex]\frac{7x-12}{BD}[/tex]

because ∠BDC = ∠ADB => sin ∠BDC = sin ∠ADB

=> [tex]\frac{4x+6}{BD}=\frac{7x-12}{BD}[/tex]

=> 4x + 6 = 7x -12

<=> 3x = 18

<=> x = 6 => CB = 4.6 + 6 = 30

Answer:

Step-by-step explanation:

EF

7y-14=2y+21

5y=35

y=7

EF=7(7)-14=49-14=35

EG

15x+7=12x+10

3x=3

x=1

EG=15(1)+7=15+7=22

Answer:

(a). 35 units ; (b). 44 units

Step-by-step explanation:

(a). 7y - 14 = 2y + 21 ⇒ y = 7

EF = 7(7) - 14 = 35 units

(b). EJ = JG

15x + 7 = 12x + 10 ⇒ x = 1

EG = 2 × (15(1) + 7) = 44 units
