Answer:
A and B
Step-by-step explanation:
Here, we want to select the statements that are sometimes true
The correct answers are that;
1. A parallelogram has congruent diagonals
This is in the case of a rectangle
Whenever we have the diagonals of a parallelogram equal, then what we have is a rhombus
b. A rhombus is a parallelogram
In this case, we have that a rhombus is a kind of parallelogram with all four sides equal and the diagonal meet at 90 degrees
The answer to this question is x=2i√2,−2i√2
Answer:

Step 1:
We need to place the numbers in descending order of the power. Here,
has the largest power, so that number goes first. We keep doing this until we end up with our final expression, placed in order based on the powers.

Step 2:
We can see that the last three numbers, 17, -7, and 6, don't have variables or powers, so we simplify by adding (and subtracting) them.

Our final equation:
