3 a + 7 + 2 a
&
7 a + 5

Is not equivalent

But how to you tell if one is equivalent or not?

ACTUALLY ANSWER IT AND NOT SAY SOMETHING JUST TO GET POINTS PLEASE xD

Answers

Answer 1

Answer:

Well what you would do is add up all the common numbers u add up 7 with 2 and 3a with 2a to get 9 ± 5a

That is a very different number to 7a ± 5

Does this help? comment if not and I will try to re-explain this

What is the measure of angle ECD?

a 79
b 90
c 9
d 17

Answers

Answer:

(A) 79º

Step-by-step explanation:

We can set up a simple equation to solve this, by using supplementary angles and the information that the problem has given:

x - 8 + 90 + 4x + 3 = 180

Now, we can solve:

x - 8 + 4x + 3 = 90

x -  5 + 4x = 90

5x = 95

x = 19

Since we found x, we can now substitute it into the equation of angle ECD:

4(19) + 3 = 79 = m<ECD (A)

Hope this helps!!

A: a translation six units up

B: a reflection across the x-axis.

C: a 180° rotation about the origin.

E: a reflection across the y-axis and then a translation of three units left.

What is a translation?

A figure is said to be translated in geometry when it is moved from one location to another without rotating, reflecting, or changing in size. To accomplish this, the figure's vertices are moved.

The following list contains each transformation that keeps a shape's congruency: -

A translation from the sixth unit up

A reflection on the x-axis is B.

a 180° rotation about the origin, denoted by C.

E: a reflection along the y-axis followed by a three-unit leftward translation.
