Which expressions are equivalent to 22c + 33d?

Mathematics
1 answer:
harkovskaia [24]3 years ago
4 0

Answer:

A, C, and E

Step-by-step explanation:

For the first one, distribute -11 to each value. A negative times a negative is a positive, so -11×-2c is 22c. -11×-3d is 33d. So the first one is right. For the third one, distribute 1/3 to each value. 1/3 of 66c is 22c, and 1/3 of 99d is 33d, so the third one is correct as well. For the last one, distribute 11 again. 11×2c is 22c and 11×3d is 33d, so the last one is correct.
