Answer:
9√xy^2
Step-by-step explanation:
according to the rule of law of indices, 3√xy=xy^(1/3) like this 9√xy^2 is the correct answer
Answer: 306in^3
method: I would split the cross-section (the trapezium at the front) into two shapes. You first have your rectangle with dimensions of 4 and 7, and your triangle with dimensions of height 4 and base 3 (10 - 7 = 3). 4 × 7 = 28in^2, 4 × 3 = 12, 12 ÷ 2 = 6in^2. The total surface area of the cross-section is therefore 6 + 28 = 34in^2. Now, to find the volume, you just multiply that by 9 which is 306in^3, which is your answer. I hope this helps!
-28n - 4 + 2n - 8 = 66
-26n - 12 = 66
-26n = 78
n = -3
Answer:385
Step-by-step explanation:
495÷9=55
55×7=385
It would be the third because it doesnt equal 12
