If a 4 × 16 rectangle has the same area as a square, what is the length of a side of the square? a. 8 b. 6 c. 10 d. 12

Area of a rectangle (Ar) = Length (L) x width (w)

Area of a square (As) = side (s) squared

     Ar = As

4 x 16 = s²

    64 = s²

 √64 = √s²

 +/- 8 = s

Since length of a side cannot be negative, disregard the -8

s = 8

a. 8

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
