Question

The length of a rectangle is twice the width. The area is 72 yd^2. Find the length and the width

Answer 1

length = x
width = 2x
2x(x)= 72 yd^2
2x^2= 72
x^2= 36
x=6

Answer 2

so the length is going to be 36 and the width is going to be 6

Answer 3

nope, width= 6
length= 12

Answer 4

Find and label for Algebra the vertex and the line of symmetry for f(x)=2(x-3)^2 The vertex is (type an ordered pair for the vertex). The equation of the line of symmetry is x=
