What is the twentieth term in the sequence 23, 43, 63, 83 …? A. 103
B. 203
C. 303
D. 403

first you would the common difference for the sequence. Subtract the first term by the second term. Subtract second term by the third term. Then to find the next value add the last given number

Step-by-step explanation:

look a the sides they are perpendicular

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
