B=3d and b=d+4
Since b=b we can say:
3d=d+4 subtract d from both sides
2d=4 divide both sides by 2
d=2

I'm assuming you mean negative integers and mixed. -3--3=? When to negatives are back to back it turns in to a positive number. The equation becomes -3+3=0.
Adding 2 negative numbers will always result in a negative value. -3+-3=-6.
A negative times a negative is always a positive . -2x-2=4
A positive integer times a negative integer will be a negative value. -3x4=-12.
A negative divided by a negative is a negative. -12/-2=-6
A positive divided by a negative is a negative. 9/-3=-3
Answer: B, C, D
Step-by-step explanation:
- A <u>rectangle</u> must have at least one right angle, not a rhombus. So, A is wrong.
- This is a specific property of a rhombus, so B is correct.
- This is a specific property of a rhombus, so C is correct.
- Since all rhombi are parallelograms, and diagonals of a parallelogram bisect each other, D is also correct.
