You would evaluate by plugging in the given number of 7 to get your answer.
Use the chain rule.
Let u = 25sin²(x), such that dy/dx = dy/du · du/dx


3/8 divided by 4/5 is the same as 3 * 5 / 8 * 4 = 15/32 or 0.46875
Answer
X1= 3-2 root3 x2= 1 x3=5 x4= 3 +2 root 3
First swap the sides then simplify the equation
Collect like terms
Move all the expression to the left to equal 0
Then collect like terms again
Reorder the terms from ^2 to ^4
Factor the expression
Change the signs
Separate into possible cases
Then sold the equation to equal 0
Then check solutions by subbing them in as x
Then you should have 4 perfect answers
Answer:
x1= -4/3 and x2= 0
