Ok, so first we distribute, you multiply the seven into everything in the parentheses next to it. So far we have, 14a+21+3(4a-2). You distribute the three into the parentheses to get, 14a+21+12a-6. You combine the like terms to get, 26a-15. You cannot simplify it any further so the answer is 26a-15.
Answer:
16 and 17
Step-by-step explanation:
16 * 17 = 272
30% because 10 out of 10 is 100%.
So 3 out of 10 is 30%.
You need to multiply 19.797 by 10 two times to reach 1979.7
