Which pair shows equivalent expressions? 3 (x + 2) = 3 x + 6 3 x + 2 x = x squared (3 + 2) 3 x + 2 = 3 (x + 2) Negative 3 (2 + x) = negative 6 x minus 3

Answers

Answer 1

Answer:

Answer:

The first pair shows equivalent expressions.

Step-by-step explanation:

3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6

The first equation is 3(x+2)=3x+6

Therefore, the first pair shows equivalent expressions.

Answer 2

Answer:

Answer: the answer is a.3 (x + 2) =

Step-by-step explanation: because when opening the equation u multiply 3 times x and 3 times 2 so the final aswer is 3x+6

Operation and simplify the answer fully. (9x)/(5)*(5)/(4x^(2)) Submit Answer

Answers

Answer:

To simplify the expression (9x/5) * (5/4x^2), we can cancel out common factors.

= (9x * 5) / (5 * 4x^2)

= (45x) / (20x^2)

= (9/4) * (x / x^2)

= (9/4) * (1 / x)

Therefore, the simplified expression is (9/4) * (1 / x) or (9 / 4x).

Step-by-step explanation:

Final answer:

To solve the given expression $(9x)/(5)*(5)/(4x^(2)$ , we multiply the numerators together and the denominators together. Simplifying further by canceling out common factors and dividing by x, the final simplified expression is 9/(4x).

Explanation:

To solve the given expression: $(9x)/(5)*(5)/(4x^(2)),$ we multiply the numerators together and the denominators together.

This gives us: $(9x * 5)/(5 * 4x^2).$

Simplifying further, we can cancel out the common factors between the numerator and denominator, which in this case is the factor of 5.

This leaves us with: $(9x)/(4x^2).$

Now, we can simplify the expression by dividing both the numerator and denominator by x.

This leads to the final simplified expression: $9/(4x).$

A bicycle wheel makes five rotations. The bicycle travels 41.87 ft. Find the diameter of the wheel in inches. Use 3.14 for pi. The diameter of the wheel is about nothing in.

Answers

Answer:

The diameter is 32.04 Inches

Step-by-step explanation:

If the Bicycle makes 5 rotations and it equals 41.87 ft

Then 1 rotation around the circumference is

41.87/5 = 8.374 ft

Circumference = $\pi d$

8.374 = 3.14*d

Divide both sides by 3.14

d = 8.374/3.14

d = 2.67 ft

To convert feet to inches, we multiply by 12

d = 2.67*12 inches

d = 32.04 Inches

a company manufactures and sells novelty Mugs. the manufacturing cost consist of a fixed cost of R8000 and a variable cost of R15 rand per mug. the mugs are sold at R35 each. assume a linear profit function. determine the profit function

Answers

ok so

8000=cost
profit-8000
then
another cost is 15rand per mug
but profit of 35 rand
35-15=20
profit of 20rand per mug

profit=R20m-8000
where m=number of mugs sold
(R20 means 20 rand)

f(m)=R20m-8000

The pyramid of khagra,in Egypt,is 488 feet tall. The Eiffel Tower,in France,is 1,063 feet tall. How much taller is the Eiffel Tower than the Pyramid of Khafra?

Answers

Answer:

The Eiffel Tower in France is 575 feet taller than pyramid of khagra.

Step-by-step explanation:

We are given the following in the question:

Height of pyramid of khagra = 488 feet

Height of Eiffel Tower in France = 1,063 feet

Difference in height =

= Height of Eiffel Tower in France - Height of pyramid of khagra

$=1063 - 488\n= 575\text{ feet}$

Thus, the Eiffel Tower in France is 575 feet taller than pyramid of khagra.
