Answer: 3t^2-9t+2
Step-by-step explanation: im assuming you meant +2. First you need to distribute 3t^2-15t+6t+2 and then you need to combine like terms.
Answer: (or )
Step-by-step explanation:
The area of a rectangle can be calculated with the following formula:
Where "l" is the lenght and "w" is the width.
In this case we know that the length of a flowerbed is 4 times as long as its width. This can be expressed as:
We know that the width of the flowerbed is:
Therefore, substituting the width into , we get that the length is:
Finally we can substitute the width and the lenght into the formula for calculate the area of a rectangle:
(or )

5.495
Step-by-step explanation:
You‘re incorrect, because I put it in a calculator and it said 5.495. The image shows proof that 5.6 - 0.105 = 5.495
Hope this helps! :)
the volume of a right-circular cylinder is V = πr²h, however, this cylinder on 6) is not a right-circular cylinder, meaning, the its altitude is not going straight up making a right-angle with the ground, is all slanted.
now, let's recall Cavalieri's Principle,
solids with the same altitude and cross-sectional areas at each height have the same volume.
so, though this cylinder is slanted, its cross-sectional areas are the same as a right-circular cylinder and thus its volume is also V = πr²h, so yes, is correct.
7)
the area of a parallelogram is A = bh.
so the volume of this solid will simply be the area of the upfront parallelogram times the depth or length of 5x.
