Answer:
I believe #20. is A
Step-by-step explanation:
because if you use distributive property and multiply the 5 to the () numbers you will get your original question.
Also, i cant see all of the options for #21.
It’s -37 because -20-17=-37
Here, 4/7 * 5
Multiply numerators together, and denominators together
It would be: 4 * 5 / 7 * 1 = 20/7
So, your final answer is 20/7
Hope this helps!
