Answer:
It could be any of them.
Step-by-step explanation:
First off, It could be said that (2c-d)(2c-d) doesn't belong because it includes two subtractions signs and none of the others do.
Secondly, It could be said that (2c+d)(2c-d) doesn't belong because it includes one subtraction sign and one addition sign and none of the others do.
Thirdly, It could be said that (2c+d)(2c+d) doesn't belong because it includes two addition signs, and none of the others do.
Finally, it could be said that (c+d)(c+d) doesn't belong because it doesn't have a multiplying factor of 2 within the parentheses.
I hope this helps :)
Answer:
Step-by-step explanation:
Statement is not true because
0 is not equal not 38
No x here.
Can you take a picture of the problem?
Answer: x = 34º, y = 146º, z = 146º
Step-by-step explanation:
Adding the angles inside a triangle gives you 180º. So
85 + 61 + x = 180
146 + x = 180
x = 34º
x and y are supplementary, so y = 180 - x = 180 - 34 = 146º.
y and z are equal (vertical angles), so z = 146º.
