The answer is 20 because adding 10 twice is 2. And the answer is 10 times 2 so u have to add 10 twice for the product
Answer:
B and D.
You still need to take square roots the normal way, so square root of 4 and 36 is 2 and 6. 2/6 simplified is 1/3. Thus, the answers are B and D
Hyp^2 = a^2 + b^2
sqrt (hyp) = 2
hyp = 4
hyp^2 = 16 then from above a^2 + b^2 = 16
Look at the number in the thousands place. This number is 6. Now look at the number after it. It is 4. 4 is less than 5 so you keep 6 the same. Now you make the rest 0s, except for the 1 before the 6. The estimate would be 16,000.
