Using the identity:

, we get:

There are two solutions to this equation:
1) 
Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2)
Therefore, there are 3 solutions to the given trigonometric equation.
6 apples + 4 peaches = 10 pieces of fruit
First choice is an apple = 6 /10 = 3/5
Now, there are:
5 apples + 4 peaches = 9 pieces of fruit
Second choice is a peach = 4 /9
Multiply the 2 fractions:
3/5 x 4/9 = 12/45 = 4/15
Answer= 4/15 (A)
Step-by-step explanation:
1/2 ÷ 3/4 = 1/2 × 4/3 = 4/6
a = 2
b = 4
c = 3
d = 4
e = 6
It is necessary when you are getting into multiplying from the outside of parenthesis and multiplying variables inside of parenthesis.
ex: 5(3 + 3x)
5 * 3 = 15
5 * 3x = 15x
so final set up would be 15 + 15x
G(f(x))= (7x+8)^4
g(f(x))= (7(0)+8)^4
=(0+8)^4
=8^4
=8•8•8•8
=4,096
