Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).
It is given that tanα=3.
Sinα(Sinα) = [], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α = .
Cos4α =

a function with a graph that is a non-vertical straight line, which can be represented by a linear equation in the form of y = mx + b
Answer:
x = -2.5 or -5/2
Step-by-step explanation:
1. Solve
2x = 3x + 10/4
-x = 10/4
x = -10/4
x = -2.5
2. Check Answer
2( -2.5) = 3( -2.5) + 10/4
- 5 = - 7.5 + 10/4
-5 = -5
