Answer:

A and D

Explanation:

A. 2 multiply by 4x give 8x and 2 multiply by 2 give 4 so the answer is 8x+4

D. When we expand the bracket, 2 multiply by 3x give 6x and 2 multiply by 2 give 4 and 2 multiply by x give 2x so the answer will be 6x+4+2x and we will gather the like terms so it will be 6x+2x=8x so the final answer is 8x+4

Answer:

$2(4x + 2)$

and

$8x + 4$

Step-by-step explanation:

Because if you simplify the equation theb you get 8x+4 therefore D is equivalent to it. A is also equal to D which make it equivalent to the equation as well.

Sarai is mixing a solution. She pours all the liquid from a full small beaker into a larger beaker. The liquid fills the large b

n200080 [17]

Answer:

2000 ml

Step-by-step explanation:

Given: Sarai pours all the liquid from a full small beaker into a larger beaker.

The liquid fills the large beaker to 15% of its capacity.

The small beaker holds 300 ml.

Lets assume capacity of large beaker to hold be "x".

As given, Sarai pours all the liquid from a full small beaker into a larger beaker

∴ $15\% \times x= 300\ ml$

⇒ $0.15x= 300$

Dividing both side by 0.15

⇒ $x= \frac{300}{0.15}$

∴ $x= 2000\ ml$

Hence, the large beaker can hold 2000 ml of liquid.

eight more than the product of four and a number is equivalent to seven less than the same number in equation form.

Georgia [21]

4n + 8 = n - 7
(In which 'n' represents the unknown number)

(4n + 8): "Eight more than the product of four and a number"

(= n - 7): "Is equivalent to seven less than the same number in equation form."

Subtract 8 from both sides:
4n = n - 15

Subtract n from both sides:
3n = -15

Divide both sides by 3:
n = -5
