43. Simplify (k – 5) - (k2 + 8).
A - k² + k + 3
B k2 + k + 13
C k²+k+3
D -k2 + k – 13

D.-k^2+k-13

Step-by-step explanation:

(k-5)-(k^2+8)

Expand the brackets. Remember brackets mean to multiply.

k*k^2= k^2+k

-5*+8= -13

Add values together.

k^2+k-13

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.
