Step-by-step explanation:
A rhombus has four equal sides but of varying angles. A rhombus has two lines of symmetry (vertical and horizontal), an order of two, and the angle of rotation of 180 degrees.
Answer:
Explanation:
To find the difference (3c - d)² you should recognize that it is the square of a difference of two terms.
The square of the difference of two terms is a special case that you should remember: it is equal to the square of the first, minus twice the product of the first and second, plus the square of the second:
For the binomial (3c - d)² you have that:
Thus:
- (3c -d)² = (3c)² - 2(3c)(d) + d² = 9c² -6cd + d² ← answer
