What is the angle of rotation about c that maps the solid figure to the dashed figure?

a. 90 degrees
b. 180 degrees
c. 270 degrees
d. 360 degrees

270 degrees

Step-by-step explanation:

You could cut out the shape, or draw it on your book, and rotate it around a straight ruler to get a visual.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
