Answer:
y==(x+2)²-4
Step-by-step explanation:
y=x²+4x
=(x+2)²-4
(x+2)²==x²+4x+4
A is correct.
Why? After opening the brackets we can see the equation as
Well the formula for a triangle is base(b) times height(h) divided by 2.
The given figure can be divided in two parts 1) Square with side 7 in 2) A right triangle with base 12 in and height 7 in.
1) Area of square = 
Side of the square is 7 in.
Area = 
2) Area of triangle = 
Area of triangle =
Area of polygon= Area of square+ Area of triangle
Area of polygon = 49+42 =91 square in.
Area =
