Answer:

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

Step-by-step explanation:

Answer:

The Bottom Right option would be correct, 6x + 9x and 3 (2x + 3x)

Step-by-step explanation:

If put 3 (2x + 3x) in standard form, it would result in;

3 * 2x = 6x

3 * 3x = 9x

Therefore

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

The perimeter of a square is 100 feet. What is the length of one of its​ sides? Explain your work.

Answers

Answer:

25

Step-by-step explanation:

to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides

you just divide 100/4=25

4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25

Each side is 25

Answers

Answer:

Valentino needs 1 [tex]\frac{3}{4}[/tex] more pounds of chicken for the recipe.

Step-by-step explanation:

You just need to know how to subtract fractions.

Valentino needs 4 and 1/2 pounds of chicken for a recipe, and he already has 2 and 3/4. We want to know how many more pounds of chicken we need, so you subtract.

4 1/2 - 2 3/4 = 4 2/4 - 2 3/4

= 1 3/4

Valentino needs 1 and 3/4 pounds of chicken still.

A.

Clearly, the two expressions are not equivalent.

B.

➡ 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 )

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

1 gallon is 4 times 1/4 of a gallon.
