Answer:
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
Step-by-step explanation:
A quadratic equation has the highest power of x being squared
x^2 -2x = 4x+1
2x^2 +12x = 0
9x^2 +6x -3=0
These are all quadratic equations
The formula for calculating the perimeter of the parallelogram is p/2-b=c.
The formula for calculating the perimeter of a parallelogram with sides b and c, for c.
<h3>
What is the perimeter of the parallelogram?</h3>
The perimeter of a parallelogram is the total distance enclosed by its boundary. Since the parallelogram is a type of quadrilateral, thus it has four sides.
Substracting 2b on both side
p = 2b+2c
-2b -2b
p -2b =2c
divide both sides by 2
p/2 -b =c
Therefore we get the formula for calculating the perimeter of the parallelogram is p/2-b=c.

Answer:
b =
Step-by-step explanation:
To clear the radicals square both sides
= ( cross- multiply )
(6 - a)(8 + b) = b - 7 ← expand factors on left using FOIL
48 + 6b - 8a - ab = b - 7 ( subtract 48 from both sides )
6b - 8a - ab = b - 55 ( add 8a to both sides )
6b - ab = b - 55 + 8a ( subtract b from both sides )
6b - ab - b = 8a - 55, that is
5b - ab = 8a - 55 ← factor out b from each term on the left side )
b(5 - a) = 8a - 55 ← divide both sides by (5 - a)
b =
