When the leading coefficient is 1,
If the constant ( c term) is a perfect square and the b term is 2* the square root of the c term.
Ex.
x*2 + 10x + 25
2*5 = 10 5*5=25
Ex.
x^2 - 12x + 36
2 * -6 = -12 6*6=36

If Cp = Rs 660, Loss percent = 5% find Sp​
Aneli [31]

Answer:

SP = 627 Rs

Step-by-step explanation:

Percentage loss is calculated as

\frac{CP-SP}{CP} , then

\frac{660-SP}{660} = 5% = 0.05 ( multiply both sides by 660 )

660 - SP = 33 ( subtract 660 from both sides )

- SP = - 627 ( multiply both sides by - 1 )

SP = 627 Rs

Find the slope between the following coordinates. (6,4)&(6,-2)​
Grace [21]

Answer:

slope is undefined

Step-by-step explanation:

calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (6, 4 ) and (x₂, y₂ ) = (6, - 2 )

m = \frac{-2-4}{6-6} = \frac{-6}{0}

division by zero is undefined, therefore the slope of the vertical line is undefined.
