Answer:
Step-by-step explanation:
In this question we will solve the polynomials by adding or subtracting the similar terms.
1). (-3x² - 8x + 2) + (-5x² - 9x - 2)
= (-3x²- 5x²) - (8x + 9x) + (2 - 2)
= (-8x²) - 17x + 0
= -8x² - 17x
2). (-2x² + 7x - 1) - (8x² - 6x + 5)
= (-2x² - 8x²) + (7x + 6x) - (1 + 5)
= -10x² + 13x - 6
3). (5x²- 5xy - 10y²) + (5x²+ 5xy + 10y²)
= (5x² + 5x²) + (-5xy + 5xy) + (-10y² + 10y²)
= 10x²
4). (2 + 8x + 4x²) - (9 + 6x + 2x²)
= (2 - 9) + (8x - 6x) + (4x² - 2x²)
= -7 + 2x + 2x²
5). (4x³ + 5x²+ 3x) - (3x³ + 6x²- 1)
= (4x³ - 3x³) + (5x² - 6x²) + 3x + 1
= x³- x² + 3x + 1
In hexadecimal, the number is expressed in 16 digits(the value would be 0-15). The digit varies from 0-9 for first 10 digits, then A-F for 6 last digits.Number 21 would be equal to 16+5. the first 16 is expressed as "1" and 5 is expressed as 5 so the answer would be 0x15
Answer:
Statement A is true
Step-by-step explanation:
Here, we want to select the correct statement
the correct answer here is that pentagon ABCDE is congruent to A’B’C’D’E
A 180 degrees counterclockwise rotation will only turn (x,y) to (-x,-y)
It doesn’t change the distance between the points which corresponds to the length of the sides of the pentagon
This means that the side lengths will be exactly the same and so, the two pentagons are congruent
