Answer:

2(3x+2y) and 6x+4y

Step-by-step explanation:

If we expand all of the solutions and the expression we are trying to match, we can see which expression has all matching terms.

The expression we are matching to can be expanded to:

2(2x+4y+x-2y)

4x+8y+2x-4y

6x+4y

Solution 1: NO

2(x+5y) and 2x+12y

2x+10y and 2x + 12y

Solution 2: NO

2(x+2y) and 2x+4y

2x+4y and 2x+4y

Solution 3: YES

2(3x+2y) and 6x+4y

6x+4y and 6x+4y

Solution 4: NO

2(3x+6y) and 6x+12y

6x+12y and 6x+12y

4. Write the ratio 25c to R3,50 in its simplest form.

suter [353]

Answers:

25c= 1/2

Then R3.50 is 3/50

Step-by-step explanations:

25c as a fraction is 25/50, so you have to simplify 25/50 to its simplest form , and you get the result of 1/2

For this you have to first find the GCD (or HCF) of numerator and denominator. GCD of 3 and 50 is 1.

3 ÷ 150 ÷ 1.

Reduced fraction: 350. Therefore, 3/50 simplified to lowest terms is 3/50.
