The answer is-B (x-9) (x-9)
angle A = 30
(2x-9) = (2x+21)
+9 +9
2x=2x+30
-2x -2x
=30
Cupcakes —> x
Flies —> y
y-x=1 ————1
x-y/2=1 ———1
y-x=x-y/2
2x=3y/2
4x=3x
x=3y/4
Substitute x in For 1
y-3y/4= 1
y/4=1
y= 4
x=3
Answer:
Step-by-step explanation:
4. f(x) = √(x + 4)
f(5) = √(5+4) = √(9) = 3
5. g(x) = x^12 - x^5
g(-1)= (-1)^12 - (-1)^5
1 - (-1) = 1 + 1 = 2
