Answer:
Length of unpainted strip of each part of the road = 9 yard
Step-by-step explanation:
Total length of the road = 208 yard
When it is divided into 16 equal parts,
length of each part = 
= 13 yard
Mr.Ward paints 4 yard long strips in each part .That is he does not completely paint the part but paints only a small section of each part.
Length of unpainted strip of each part of the road = length of each strip - length of strip painted by Mr.Ward
Length of unpainted strip of each part of the road = 13 - 4
Length of unpainted strip of each part of the road = 9 yard
Answer: x = -1
Step-by-step explanation:
Answer:
Converting the equation 
into completing the square method we get: 
Step-by-step explanation:
we are given quadratic equation:
And we need to convert it into completing the square method.
Completing the square method is of form: 
Looking at the given equation
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides
So, converting the equation into completing the square method we get:
