Answer:
y = ± 
Step-by-step explanation:
Given
x = a - 2by² ( add 2by² to both sides )
x + 2by² = a ( subtract x from both sides )
2by² = a - x ( divide both sides by 2b )
y² =
( take the square root of both sides )
y = ± 
This polynomial is a difference of two squares.
A difference of two squares factors into the product of a sum and a difference.
Answer:
Total area = 51 in²
Step-by-step explanation:
Section the shape into a rectangle and a triangle.
Area of a rectangle = width x length
⇒ area = 6 x 7 = 42 in²
Area of a triangle = 1/2 x base x height
⇒ area = 1/2 x (6 - 3) x (13 - 7) = 9 in²
Total area of composite shape = 42 + 9 = 51 in²
