Since you didn't give the diagram, we can't find the exact answer. However, I can give you some guidance so you can find the correct answer.

You are looking for the value that you multiply to get from the first shape to the second. Just write and solve an equation with k as the scale factor.

Here is an example of a dilation from 5 to 20.

5k = 20 Divide both sides by 5
k = 4

Answer:

See Explanation

Step-by-step explanation:

Given

$\triangle ABC = \triangle DE F$

Required

Which would not prove the similarity

$\triangle ABC = \triangle DE F$ implies that:

The following angles are congruent

$\angle A = \angle D$

$\angle B =\angle E$

$\angle C =\angle F$

And the following lengths are congruent

$AB = DE$

$BC =EF$

$CA = FD$

The options are not clear; so, it's a bit difficult to select the correct option.

<em>Any of the options that is different from the above list of 6 congruent pairs is the answer to your question.</em>

The set of numbers 1, 3, 7, 11, 15, and 36 contains all possible values for q. What value of q makes the following equation true

marta [7]

Answer:

q = 7

Step-by-step explanation:

4q + 9 = 37

If a letter and a number are together it means multiply.

<em>Substitute 7 into the equation:</em>

4(7) + 9 = 37

28 + 9 = 37

So q must equal 7
