X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3
400÷4/7=700

The cost of 300 cm fabric is $15.
Step-by-step explanation:
Given,
Cost of fabric is $5 per meter.
To find the cost of 300 cm fabric.
1 m = 100 cm
We will apply unitary method.
Cost of 100 cm of fabric is $5
Cost of 1 cm of fabric is $
Cost of 300 cm of fabric is $
= $ 15
Hence,
The cost of 300 cm fabric is $15.
