Answer:
Area: 
Step-by-step explanation:
Since all sides of a square have equal lengths, the area of the square is 
(a = length of a side).
Since the length of the side of the square is given (is 3cm), the area of the square is 
= 
Answer:
a = 1 b = -1.
Step-by-step explanation:
Suppose the quotient when you divide x^4+x^3+ax+b by x^2 + 1 is
x^2 + ax + b then expanding we have:
(x^2 + 1)(x^2 + ax + b)
= x^4 + ax^3 + bx^2 + x^2 + ax + b
= x^4 + ax^3 + (b + 1)x^2 + ax + b Comparing this with the original expression:
x^4 + x^3 + 0 x^2 + ax + b Comparing coefficients:
a = 1 and b+ 1 = 0 so b = -1.
Answer:
481.5
Step-by-step explanation:
The music art museum is divided into 6 sections
Each section contains the same timert of tiles
There are 2889 tails total
Therefore the number of tiles in each section can be calculated as follows
= 2889/6
= 481.5
Hence there are 481.5 tiles in each section
Answer:
Step-by-step explanation:
6-4[x+1-(y+3)]+6y
6-4[x+1-y-3]+6y
6-4[x-2-y]+6y
6-4x+8+4y+6y
14-4x+10y
