Answer with Step-by-step explanation:
Let 
Substitute n=2
Then 

Hence, P(n) is true for n=2
Suppose that P(n) is true for n=k >1

Now, we shall prove that p(n) is true for n=k+1

LHS

Substitute the value of P(k)






LHS=RHS
Hence, P(n) is true for all n >1.
Hence, proved
I think the answer is this,I am not sure.....
Answer:
The answer is 15x+5
Step-by-step explanation:
1. Combine like terms (numbers with the same variable) (just add 7 & 8 and add an x)
2. Bring the rest down
3. After you combined like terms make sure you bring the variable down to it's proper spot
5. Hope this helps.. :)
In the shown picture, To find the shaded area we need to find the total area of the square, subtracted by the area of the circle.
the area of the shaded region = the area of the square - the area of the circle
the area of the square = L² = 7² = 49 cm²
the area of the circle = πr² = 3.14 x 3.5² = 38.5 cm²
the area of the shaded region = 49 - 38.5 = 10.5 cm²
