Answer:
the answer is 180°
Step-by-step explanation:
x+45°+55°+80°=360°
x+180=360°
x=360°-180°
x=180°
Answer: 66
Step-by-step explanation:
Use the rational root theorem
a0=16, an=1
The dividers of a0: 1,2,4,8,16 The dividers of an:1
Therefore check the following rational numbers: +- 1,2,4,8,16/1
4/1 is a root of the expression, so factor out x-4,
compute (x^4+13x^3-64x^2-20x+16)/(x-4) to get the rest of the equation:
x^3+17x^2+4x-4
=(x-4)(x^3+17x^2+4x-4)/x-4
which will leave you with answer B
x^3+17x^2+4x-4
Answer:
Area of Living Room = 300 square feet
Step-by-step explanation:
According to question ,
The area of bathroom = 35 square feet
And it is mention that area of bathroom is 25 sqft less than 
area of living room .
Thus , as per question ,
Area of bathroom = times area of living room - 25 sqft
Or, 35 sqft = times area of living room - 25 sqft
Or, 35 sqft + 25sqft = times area of living room
Or, 60 sqft = times area of living room
∴ Area of living room = 60 × 5
Hence , Area of living room = 300 square feet .
Answer:
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
Step-by-step explanation:
cost of the cleaning is calculated from the area of the carpets
C= the cost of the cleaning a= the area of the carpets.
Cost of the cleaning, C is the dependent variable
Area of the carpet, a is the independent variable
A dependent variable is a variable which depends on other factors to exist. They take their values based on other factors. Their value is changed as a result of a change in independent variable
An independent variable is a variable which does not change as a result of the change in other factors. They take their values irrespective of external factors around them.
