To find the number of even factors, we can multiply the number of odd factors by the power of 2 (not the power of 2 + 1!!!). For 540, we have (3 + 1)(1 + 1)(2) = 16 even factors.

Answer:
a = 15
Step-by-step explanation:
The Law of Cosines
a^2 = 13^2 + 14^2 - 2(13)(14)Cos(67.4)
a^2 = 169 + 196 - (364 * 0.3843)
a^2 = 365 -140
a^2 = 225
a = 15
Answer:
x/2 + 21 = 36
First we get rid of constants to isolate the variable.
In order to do that we must do the inverse operation.
Inverse operation of addition is subtraction.
-21 -21(subtracting 21 from both sides, whatever we do to the left side we do it to the right side too)
x/2 = 15
inverse property of division is multiplication
x2 x2
X = 30
