4. in the diagram at the right, the dimensions of the large rectangle are (3x – 1) by (3x + 7) units. the
dimensions of the cut-out rectangle are x by 2x + 5 units. which choice expresses the area of the shaded
region, in square units?
5
3x + 7.
a. x2 + 23x - 7
b. x2 + 13x - 7
c. 7x2 + 23x - 7
d. 7x2 + 13x - 7

d.7x2+13x-78743t8u667i

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)
