Answer: Yes it does matter because you can't add the like terms if they aren't the same.
Step-by-step explanation: 2x+8y you can't add these two because they don't have the same like terms.
Answer:2
Step-by-step explanation: 2x2=4 therefore 4 is double 2
- Following the order of operations, we do parenthesis first.
- Multiply out the value against the parenthesis.
- This leaves us with 20 over 20. 20 goes into 20 only 1 time, so our final answer is 1.
Question 1:
We can use the rule of exterior angle of triangle, where the exterior angle is equal to the sum of the other 2 interior angles of the triangle except for the adjacent one.
So, we can calculate angle 1 by adding up the 2 given angles.
Angle1 = 62° + 57°
=119°
=answer C.
Question 2:
We can also apply the rule above, but first we have to calculate the remaining angle of the triangle first.
For this, we have to use the angle sum of triangle. All 3 interior angles of triangle should add up to 180°.
Let that remaining angle be x.
X = 180° - 62° - 57°
X=61°
Now we can apply the rule of exterior angle of triangle.
Angle 1 = 62° + 61°
=123°
=answer D.
