Which Two Expressions Are Equivalent? AB C Or D?

Answers

Answer 1

D because it's d and I know it's d

Answer 2

[tex]\longrightarrow{\green{D.\:6x\:+\:9x\:and\:3\:(\:2x\:+3x\:) }}[/tex] ✔

[tex]\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\orange{:}}}}}[/tex]

A.

z + z + z = [tex]{z}^{3}[/tex]

➡ 3z ≠ [tex]{z}^{3}[/tex]

➡ L. H. S ≠ R. H. S

Clearly, the two expressions are not equivalent.

B.

13x + 9 - 2x = 15x + 9

➡ 11x + 9 ≠ 15x + 9

➡ L. H. S ≠ R. H. S

The two expressions are not equivalent.

C.

11 x² + 4x + 9 ≠ 15 x² + 9

➡ L. H. S ≠ R. H. S

The two expressions are not equivalent.

[tex]\boxed{D.}[/tex]

6x + 9x = 3 ( 2x + 3x )

➡ 3 ( 2x + 3x ) = 3 ( 2x + 3x )

➡ L. H. S = R. H. S

Since L. H. S is equal to R. H. S., the two expressions are equivalent.

10.  n = 21

11.  44 = v

12.  c = 35

Step-by-step explanation:

9.   9y = 72

Divide each side by 9

9y/9 = 72/9

y = 8

10.  3n = 63

Divide each side by 3

3n/3 = 63/3

n = 21

11.  4 = v/11

Multiply each side by 11

4*11 = v/11*11

44 = v

12.  c/7 = 5

Multiply each side by 7

c/7*7 = 5*7

c = 35

y=8

How many millimeters are equal to one kilometer?

Metric
1 kilometer = 1,000 meters
1 meter = 100 centimeters
1 meter = 1000 millimeters
1 centimeter = 10 millimeters

Answers

Answer: The answer would be 1,000,000, or one million.

Step-by-step explanation:

There are 1000 millimeters in a meter, and there is the same number of meters in one kilometer. So to solve for how many millimeters are in one kilometer, just multiply 1000 by 1000 to get 1,000,000. Hope this helps!

It will equal 1,000,000 kilometres
