The vertices of Figure ABCD are A(1,1) B(2,3) C(4,3) and D(5,1). If figure ABCD is reflected over the line y = - 1, find the coordinates of vertex B'.

(23*2)-12=x     x=34

step-by-step explanation:

the area of the rectangle is 35units^2.

step-by-step explanation:

graph it and find the distance.

it is a 5*7 rectangle.

therefore the area is 35units^2.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
