Answer:
x = 1
Step-by-step explanation:
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
Answer:
x = 130
Step-by-step explanation:
The sum of the exterior angles of a polygon is always 360
140 + x + 56+ 34 = 360
Combine like terms
230 +x = 360
Subtract 230 from each side
230+x-230 = 360-230
x =130
The system of equations representing the number of Blue-ray discs and DVD's after t months are:
507 + 26t
925 - 12t
Each month, the number of DVD's sold decreases by 12, this can be modelled as:
number of DVD in opening month - (monthly decrease x number of months)
Number of DVD's in t months = 925 - 12t
Each month, the number of Blue-ray discs sold increases by 26, this can be modelled as:
number of blue-ray discs in opening month + (monthly increase x number of months)
Number of Blue-ray discs in t months = 507 + 26t

Answer:
Hi,can you please answer mine too I really need the answer because I have to pass it tomorrow morning at my 1st class I really need the answer right now I hope you can help me the question is 6-10:(
Step-by-step explanation:
about your question I'll just put it in the comment section:)you can just check it there
P=2(L+W)
P=364
L=99
sub and find W
364=2(99+W)
divide both sides by 2
182=99+w
subtract 99 from both sides
83=W
w=83ft
