18. The shape is only shifted to a different location and orientation but remains the same size so this is congruent.

19 and 20 are both scaled to a different size so they are both similar.

Define equivalent expressions. Give an example of two equivalent expressions.

Tasya [4]

Answer:

Hello There!

Step-by-step explanation:

Equivalent expressions are expressions that work the same even though they look different.

Examples of two equivalent expressions are:

-4(x + 2) and 4x + 8

-2y+5y−5+8 and 7y+3

These are equivalent expressions as they have the same value.

hope this helps,have a great day!!

parker correctly answered 70% of the questions on his math test. If he answered 35 questions correctly, how many questions were

Alexandra [31]

Let the total number of questions in the math test be defined by the variable x.

Now, we know that Parker correctly answered 35 questions. These 35 questions make 70% of the total number of questions on his math test.

The information we have above can be expressed as an equation given below:

70% of x=35

This can be rewritten as:

$\frac{70}{100}x=35$

Thus, to find the total number of questions we will have to isolate x.

$\therefore x=\frac{35\times 100}{70}=50$

Therefore, there were a total of 50 questions in the math test.

Consider the proof.

fiasKO [112]

Answer:

Correct choice is B

Step-by-step explanation:

In step 4 were proved that $\triangle ABC\sim\triangle DEC.$

By definition, similar triangles have proportional lengths of corresponding sides. To the side AB corresponds side ED, to the side AC corresponds side DC and to the side BC corresponds side EC. Thus,

$\dfrac{AC}{DC}=\dfrac{BC}{EC}.$
