Answer two questions about Equations AAA and BBB: \begin{aligned} A.&&2x-1+3x&=0 B.&&5x-1&=0 \end{aligned} A. B. 2x−1+3x 5x−1 =0 =0 1) How can we get Equation BBB from Equation AAA? Choose 1 Choose 1 (Choice A) A Add/subtract the same quantity to/from both sides (Choice B) B Add/subtract a quantity to/from only one side (Choice C) C Rewrite one side (or both) by combining like terms (Choice D) D Rewrite one side (or both) using the distributive property 2) Based on the previous answer, are the equations equivalent? In other words, do they have the same solution? Choose 1 Choose 1 (Choice A) A Yes (Choice B) B No

The given equations are equivalent and this can be determined by combining like terms by using the arithmetic operations.

Given :

The following steps can be used in order to determine the correct statement:

Step 1 - Write the given equations.

2x - 1 + 3x = 0

5x - 1 = 0

Step 2 - The arithmetic operations can be used in order to determine the correct statement.

Step 3 - Add 2x and 3x in equation (1).

5x - 1 = 0   --- (3)

Step 4 - Compare both equations (3) and (2). It can be concluded that both equations are identical.

Therefore, the correct option is C).

Required

How to get equation B from A?

Are both equations equivalent?

- How to get equation B from A?

Option C answers this question

This is shown below

Equation A can be rewritten as thus:

Collect Like Terms

This gives

At this stage, we have equation B

- Are both equations equivalent?

Yes they are:

This is shown below:

Equation A was solved in (1) above to give:

And Equation B is

Hence:

We can conclude that both are equivalent

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
