Answer:
The sum of three consecutive integers for 198 are <em>65, 66, and 67</em>
Definition of "INTEGERS"
1. a whole number; a number that is not a fraction.
2. a thing complete in itself.
Step-by-step explanation:
198 = x + x + 1 + <em>x + 2</em>
combine like numbers
198 = 3x + 3
subtract 3 from like numbers (in this case)
198 - 3 = 3x + 3 - 3
195 = 3x
divide by 3
195/3 = 3x/3
65 = x
x + 1 = 65 + 1 ---66
x + 2 = 65 +2 --67
Answer:
(x + 1) (3 x^2 + 1)
Step-by-step explanation:
Factor the following:
3 x^3 + 3 x^2 + x + 1
Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):
3 x^2 (x + 1) + (x + 1)
Factor x + 1 from 3 x^2 (x + 1) + (x + 1):
Answer: (x + 1) (3 x^2 + 1)
Since it says ESTIMATE:
round 5.9 to 6 and 3.4 to 3
6* 3 = 18
The estimate would be LETTER C 18
Answer:
336 ft²
Step-by-step explanation:
The rectangle is 13 ft long and 8 width that means we have two walls 8* 9 and two walls 13*9
Total walls area is
2*8*9 + 2*13*9 = 144 + 234 = 378 ft²
then we subtrac , areas of door, closet and windows
3 * 6.5 = 19,5 ft²
3 * 6,5 = 19,5 ft²
2 * 1,5 = 3 ft²
42 ft²
Then area to paint 378 - 42 = 336 ft²
