Filipo is building a rectangular sandbox for his younger brother. The length of the sandbox is 1 foot longer than
twice the width of the sandbox. The perimeter of the
sandbox is 29 feet.
Part A
Which equation could be used to determine w, the width,
In feet, of the sandbox?
A W + W + 2 = 29
B. W + 2W + 1 = 29
C. 2w + 2(w + 2) = 29
D. 2w + 2(2w + 1) = 29

the co-ordinates of the transformed rectangle are:

d. (0, 0), (0, 3), (-3, 3), (-3, 0)

step-by-step explanation:

from the columns of the given matrix, the co-ordinates of the rectangle before transformation are:

(0, 0), (0, 3), (3, 3), (3, 0)

r =

transformed matrix can be obtained by multiplying the given matrix by r:

columns of the transformed matrix are:

0   0   -3   -3

0   3     3     0

from the columns of the resulted matrix, we can see that the vertices of the transformed triangle are:

(0, 0), (0, 3), (-3, 3), (-3, 0)
