Answer:
40
Step-by-step explanation:
Answer:
-11, -17
Step-by-step explanation:
Since we are told it is an arithmetic sequence, we find the common difference. To find the common difference, subtract a term from the next term.
1 - 7 = -6
The common difference is -6.
1st term: 7 (We knew this.)
2nd term: 7 + (-6) = 1 (We knew this.)
3rd term: 1 + (-6) = -5 (We knew this.)
4th term: -5 + (-6) = -11
5th term: -11 + (-6) = -17
Answer: -11, -17
The distance could be calculated as follows:
d =
![\sqrt{ (5-2)^{2} + (-4-3)^2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%285-2%29%5E%7B2%7D%20%20%2B%20%20%28-4-3%29%5E2%7D%20%20%7D)
d =
![\sqrt{ 3^{2} + (-7)^{2}](https://tex.z-dn.net/?f=%20%5Csqrt%7B%203%5E%7B2%7D%20%2B%20%28-7%29%5E%7B2%7D%20)
d =
Answer:
546
Step-by-step explanation:
The lateral area is made up of 4 faces that do not includes the bases.
2 faces have dimensions 2.5 ft by 21 ft.
2 faces have dimensions 10.5 ft by 21 ft.
LA = 2 * 2.5 ft * 21 ft + 2 * 10.5 ft * 21 ft
LA = 105 ft^2 + 441 ft^2
LA = 546 ft^2
Answer: 546
Answer:
A is also 27.
B is 16 also.
Step-by-step explanation:
These are acute triangles they all almost have the same length except for the one different on the side. They would be isosceles if not for that.
