Answer:
A. 4x⁴ - 4x³ - 16x² - 16x
B. 4x⁴ - 4x³ - 16x² + 16x
Step-by-step explanation:
If you want to find the product of 2 binomial (or even polynomial) expressions, you simply need to multiply every term in one expression by every term in the other:
A.
(4x² - 4x)(x² - 4) = 4x²(x²) + 4x²(-4) - 4x(x²) - 4x(4)
= 4x⁴ - 16x² - 4x³ - 16x
= 4x⁴ - 4x³ - 16x² - 16x
B.
(x² + x - 2)(4x² - 8x) = x²(4x²) + x(4x²) - 2(4x²) + x²(-8x) + x(-8x) - 2(-8x)
= 4x⁴ + 4x³ - 8x² - 8x³ - 8x² + 16x
= 4x⁴ - 4x³ - 16x² + 16x
Descending order simply means the powers must be largest first and smallest last.
Answer:
- B. vertical line symmetry
- C. diagonal line symmetry
- D. rotational symmetry
Step-by-step explanation:
Any line through a vertex and the center of the opposite side is a line of symmetry. One of them is vertical in the figure shown. Two of them are diagonal. The three lines are 360°/3 = 120° apart, so the figure has 3-fold rotational symmetry.

Answer:
All of the above are true
Step-by-step explanation:
If you look at the first answer choice, you can see that line "s" and line "t" interest at one point. So the first answer choice is definitely true, but we have to continue looking at other answer choices to make sure.
All lines that intersect must intersect at a point, and in the photo that point is established as Point P. This makes the second answer choice also correct.
If we look at the third answer choice and the photo, we can see that point P is definitely on line t and s (when there are two lines intersecting at a point, that point is on those two lines). This shows that the third answer choice is also correct.
Since the fourth answer acknowledges that all of the other answers are correct, it is the correct answer.
