To do these problems, you need to multiply your (x - 3) by something to make it the same as the first number under your radical sign. For example, for the first step, I multiplied (x - 3) by -2x^2 to get (-2x^3 +6x^2). When you subtract it from the number under your radical like you would in regular long division, you can change its signs to cancel out the first number under the radical. The blocky-looking subtraction signs are ones I changed. Your final answer is (-2x^2-10x-27) with a remainder of -79.
Answer:
Step-by-step explanation:
Let w represent width of the rope-off section.
We have been given that a manager needs to rope off a rectangular section for a private party the length of the section must be 7.6 m the manager can use no more than 28 m of the rope.
We will use perimeter of rectangle formula to solve our given problem. We know that perimeter of a rectangle is equal to 2 times the sum of length and width.
Upon substituting our given values, we will get:
Since the manager can use no more than 28 m of the rope, so perimeter of rope-off section should be less than or equal to 28 meters.
We can represent this information in an inequality as:
Therefore, our required inequality would be .
Let us find width as:
Therefore, the width of the rope-off section should be less than or equal to 6.4 meters.

Answer:
(-9.15)
Step-by-step explanation:
We are given these following vectors:
u = (2,4), v = (-1,-1), w = (7,-2)
What is the vector for 3u + v- 2w in component form?
3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)
The answer is (-9,15).
