What is the expression (x-3)(x^2-3x-10) as a polynomial in standard form?

A polynomial in standard form only means that you put it in order of descending x values. Multiplying out those 2 factors gives us x^3-3x^2-10x-3x^2+9x+30. Combining like terms and we have x^3-6x^2-x+30. That's in standard form.

What is the area of the unshaded path
andre [41]

Answer:

114 feet

Step-by-step explanation:

the black and white will both have the same area. and given that each path is 1 ft wide and initially 12 ft long we can slowly determine the area.

x times 1 will still equal x

12(1) still equals 12 so we can just write it as 12.

12+12+11+11+10+10+9+9+8+8+7+7= 114

where I came up with this? there are a total of 12 sides if you follow the black path. and by every 2 sides the path gets shorter by 1 foot.

the white side also has 12 sides if you look. therefore both the black and the white part of the shape will have an area of 114.

Triangle ABC is isosceles (even tho' it doesn't look so).

m<BDE = m<BED because of that.

Thus, 66 degrees + 2 m<BDE = 180 degrees, and

2 m<BDE = 114 degrees.  Thus, m<BDE = 57 degrees.

Ralph Chase plans to sell a piece of property for ​$170000. He wants the money to be paid off in two waysminusa ​short-term note
PSYCHO15rus [73]

Answer:

Amount of short term note = $90,000

Amount of long term note = $80,000

Step-by-step explanation:

Data provided in the question:

Total amount = $170,000

Interest rate of short term note = 10%

Interest rate in long term note = 8%

Total annual interest paid = $15,400

Now,

Let the amount of short term interest be 'x'

thus,

amount of long term interest will be ($170,000 - x)

also,

Interest on short term note + Interest on long term note = Total interest

or

⇒ 0.10 × x + 0.08 × ($170,000 - x) = $15,400

or

0.1x + $13,600 - 0.08x = $15,400

0.02x = $15,400 - $13,600

or

0.02x = $1,800

or

⇒ x = $90,000

Hence,

Amount of short term note = $90,000

Amount of long term note = $170,000 - $90,000 = $80,000
