Yes, u would
15x + 25 = 5x + 175...subtract 5x and 25 from both sides
15x - 5x = 175 - 25
10x = 150
x = 150/10
x = 15
Answer:
where is the question i cant see it
Step-by-step explanation:
Explanation:
The key to area in polar coordinates is the formula for the area of a sector:
a = (1/2)r²θ
Then a differential of area* can be written as ...
da = (1/2)r²·dθ
Filling in the given function for r, we have ...
da = (1/2)(4cos(3θ))²·dθ = 8cos(3θ)²·dθ
The integral will have limits corresponding to the range of values of θ for one loop of the graph: -π/6 to π/6. So, the area is ...

_____
* As with other approaches to finding area (horizontal or vertical slice, for example), we assume that the differential element dθ is sufficiently small that we need not concern ourselves with the fact that r is a function of θ.
Answer:
/
Step-by-step explanation:
firstly we make two steps to simplify this question.
1st step: simplify 
to simplify this we use factorization


.....(1)
2nd step:simplify 


.....(2)
now dividing (1) and (2), we get the answer
