Area of a sector: 1/2r^2 theta
Need theta
Let x be theta for now
42.25 pi = 1/2r^2x
84.5pi = r^2x
84.5pi = 169x
x = 84.5pi/169 = roughly 1.57 in radians
Radians => degrees is 1.57 * 180/pi or roughly 90.
Hi there!
Let's use the given formula of a square (A = s^2), to figure out what the equation would be. We are looking for one side, or s here.
WORK:
81 = s^2
squareroot(81) = s
ANSWER:
The second option, root 81.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
Its A
Step-by-step explanation:
I got it right, I promise
The answer is 2x³ + 12x² + 10x - 24
(2x² + 6x - 8)(x + 3) = x(2x² + 6x - 8) + 3(2x² + 6x - 8) =
= 2x³ + 6x² - 8x + 6x² + 18x - 24 =
= 2x³ + (6x² + 6x²) + (-8x + 18x) - 24 =
= 2x³ + 12x² + 10x - 24
