Which two expressions are equivalent? A.
(d + 9) • 3 and d + (9 • 3)
B.
(d − 8) • 2 and (8 − d) • 2
C.
3(4d − 2) and 7d − 5
D.
5(3d + 6) and 15d + 30

Step-by-step explanation:

We are doing to replace d with 14

(14 + 9 equals 23) times 3 (equals 69) and 14 plus (9 times 3 equals 27) equals 41

(14 -8 equals 6) times 2 equals 12 and 8 -14 equals 6  (times 2) equals -12

3(4 times 14  equals 56-2 equals 54) times 3 equals 162 and 7 times 14 equals 98 -5 equals 93

5(3 times 14 equals 42 plus 6 equals 48) times 5 equals 240 and 15 times d equals 210 plus 30 equals 240

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.
