Answer:
(b) Both vertical and horizontal reflection
Step-by-step explanation:
The figure will be a horizontal reflection of itself about any vertical line through two of the smaller 6-pointed stars.
The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.
the pattern has both vertical and horizontal reflection
__
<em>Additional comment</em>
A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.
Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
Answer:
1) 12 units^2
2) 4 units^2
3) 2units^2
Step-by-step explanation:
count the squares
The sum of the polynomials (8x²-9y²-4x)+(x²-3y²<span>-7x) is:
1. You must add the terms whose variables and exponents are the same.
2. Let's rewrite the polynomials:
</span>
(8x²-9y²-4x)+(x²-3y²-7x)
8x²-9y²-4x+x²-3y²-7x
(8+1)x²+(-4-7)x+(-9-3)y²
3. Therefore, the result is:
9x²-11x-12y²
3. <span>What is the sum of the polynomials?
The answer is: </span>9x²-11x-12y²
Answer:
The answer is -22x² - 14x.
Step-by-step explanation:
You have to eliminate the brackets by multiplying :
Next you can simplify but there is no common terms in this expression so it remains the same.
Answer:
50 score/71.43%
Step-by-step explanation:
25/35
You need to multiply both the numerator and denominator by 2 due to the fact 70 divided by 35 equals to 2.
50/70 if you divide 50 by 70, you get 71.428- which is rounded to 71.43
