Answer:
-12
Step-by-step explanation:
f(x) = -3x^2
Let x = -2
f(-2) = -3( -2)^2
= -3 ( 4)
= -12
Answer:
i just think that this...
i.d.k his hair looks a little weird tho
Answer:
11. x = -16
12. k = 6
13. x = -19
14. x = -6
15. x = -20
16. Combining like terms isn't to be used on this type of problem. I'm sorry, can you guess on this one?
17. x = 19
18. n = -10
19. b = 11
20. n = 4
21. r = -6
22. n = -4
Again super sorry about question 16 :(
4 girls and 6 boys
2(2 girls) and 3(2 boys)
₄C₂ x ₆C₂
= 6 x 15
= 90
Answer: 90 different teams
Step-by-step explanation:
by Pythagoras theorem :
base ²+ perpendicular ² = hypotenuse ²
base = 5cm
perpendicular = 8 cm
hypotenuse = h cm
5²+ 12² = h²
25 + 144 = h²
169 = h²
h = √ 169 = 13 cm
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you .
