Answer: x = 9
Step-by-step explanation:
x + 20 = 29
x = 9
9 + 20 = 29
Answer:
x = 25°
Step-by-step explanation:
3x + 2x + x + 30° = 180°
6x + 30° = 180°
6x = 150°
x =25°
=> 3x = 25 * 3 = 75°
=> 2x = 25 * 2 = 50°
=> x + 30° = 25° + 30° = 55°
Answer:
None of those that you listed are correct.
Step-by-step explanation:
All of the selections you've shown do not equal to 43. Sorry. :(
C=dπ and r+r=d so 3+3=6 and 6π≈18.84 so the circumference would be 18.84
Answer: Variant C
Step-by-step explanation:
f(x) = 3x^2 − 4
For finding f(-2) just replace x with - 2 like this:
f(-2)=3*((-2))^2-4=3*4-4=12-4=8
