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!
Answer: A) (2+2) x 3
Step-by-step explanation: The answer to the problem (2 X 3) + (2 X 3) is 12 so we have to find the eqaution in the answers that equals 12,
B) 2 + (3+3) is equal to 8 so that can't be the correct answer
C) 2 x 3 x 3 is equal to 18 so that can't be the correct answer
D) (2 + 3) x (3+2) simplifies to 5 x 5 which is 25 so that can't be the correct answer
So that leaves us with A) (2+2) x 3 as the correct answer because it equals <u>12</u>
The outliers are 1 and 2 because they are different from the rest of the data. All the other numbers are large like 10, 12, 9 etc. but 1 and 2 are smaller making them the ones that differ from the rest.
This is actually pretty easy. Since we want lines, we can eliminate the bottom 2. The symbol for perpendicular is an upside down T so it is B
