C. is the correct answer because (x+3)^2 is x^2+6x+9
Answer:
b
Step-by-step explanation:
Using the trigonometric identities
cot x =
and tan x =
thus
+ tanΘ × cosΘ
=
+
× cosΘ
= cosΘ ×
+ sinΘ
= sinΘ + sinΘ
= 2sinΘ → b
5x -3 = 12
5x -3 + 3 = 12 + 3 [Add 3 to each side]
5x + 0 = 15 [Evaluate]
5x/5 = 15/5 [Divide each side by 5]
1x = 3 [Evaluate]
The answer I get is the number 3.
It’s the last one & the second one
