A.
19.50
B.
19.15
C.
18.95
D.
18.05
Correct Answer: 19.50
Explanation
m = 3, p = -3, q = 7 and r = 5/2 m(p+q+r) = 3(-3 + 7 + 5/2) = 3(4 + 5/2) = 3(4 + 21/2) = 3 * 61/2 = 3 * 13/2 = 39/2 = 19.50
m = 3, p = -3, q = 7 and r = 5/2 m(p+q+r) = 3(-3 + 7 + 5/2) = 3(4 + 5/2) = 3(4 + 21/2) = 3 * 61/2 = 3 * 13/2 = 39/2 = 19.50THIS WEEK's
