Answer:
x= -2
Step-by-step explanation:
Simplifying 5x + 45 = 35 Reorder the terms: 45 + 5x = 35 Solving 45 + 5x = 35 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-45' to each side of the equation. 45 + -45 + 5x = 35 + -45 Combine like terms: 45 + -45 = 0 0 + 5x = 35 + -45 5x = 35 + -45 Combine like terms: 35 + -45 = -10 5x = -10 Divide each side by '5'. x = -2 Simplifying x = -2
We'll first simplify both sides of the expression to get (simply using the distributive property):

Then, we can simplify a little bit:

To solve for n, we have to isolate it. Let's subtract 3n from both sides to further simplify it:

Then, add 18 to both sides to get the value of n:

And that's your answer. If you have questions on how I got that, feel free to ask!
Answer:
3
Step-by-step explanation:
Period of a function is the period after which the function attains the same value
in the graph attached with this problem we can see that
f(0)=1
the value of x for which function f(x) attains the value 1 again is at
x=3
f(3)=1
similarly , we see
f(6)=1 , f(9)=1
Hence we see that after every increased value of x by 3 units , we attain the same value of function . hence the period of the function is 3
