Answer: Third option.
Step-by-step explanation:
To solve this exercise it is important to remember the following:
1) By definition, equivalent expression have the same value, but they look different.
2) The multiplication of signs:

Then, given the following expression provided in the exercise:

You need to distribute the postive sign:

And finally, you must add the like terms:

As you can notice, the expression obtained matches with the expression shown in the third option.
Answer:
Step-by-step explanation:
Two angles each =x because both are equal.
All triangles have angles adding to 180 degrees
The angle that isn't = x is 82 degrees.
x + x + 82 = 180 Subtract 82 from both sides
2x + 82 - 82 = 180 - 82 Combine
2x = 98 Divide by 2
2x/2 = 98/2
x = 49
angle 1 = 49
angle 2 = 49
angle 3 = 82
No a rate is a special type of ratio
"A ratio is a comparison of two numbers or measurements. The numbers or measurements being compared are called the terms of the ratio. A rate is a special ratio in which the two terms are in different units."
Answer:
The answer is probably A, but you typed it in wrong so I do not know. I can only guess because the others do not seem to be correct either. I have graphed them on Desmos. The screenshot is below.
