Answer:
Step-by-step explanation:
Area of the specified region = Area of larger circle - Area of smaller circle
Larger circle:
r = 16 + 3 = 19 m
Area = πr²
=π * 19 * 19
= 361π m²
Smaller circle:
r = 16 m
Area = πr²
=π * 16 * 16
= 256π m²
Area of the specified region = 361π - 256π = 105π m²

Step-by-step explanation:
Answer: opposite of -5 is positive 5 so it’s choice C
Answer:
1. 2x(-3x - 1)
-6x^2 - 2x
2. -x(4 + 2x)
-4x - 2x^2
3. -5x(-2x + 4)
10x^2 - 20x
4. x(-2x - 2) + 3(-4x - 6x)
-2x^2 - 2x - 12x - 18x
-2x^2 - 32x
5. 2xy(-3x - 5y) + 4y(-2xy - 4x)
-6x^2y - 10xy^2 -8xy^2 - 16yx
-6x^2y -18xy^2 - 16yx
You just distribute (multiply) what's outside the parentheses with everything inside the parentheses. Then, combine like terms.
