<em>Comment on the squaring</em>
There are several ways you can find the square (x+4)².
- Use your knowledge that (x+a)² = x²+2ax+a².
- Use FOIL* to compute (x+4)(x+4) = x² +4x +4x +4² = x²+8x+16
- Use the distributive property: (x+4)(x+4) = x(x+4) +4(x+4) = x² +4x +4x +4² (same as FOIL for two binomials)
__
* FOIL is mnemonic for {First, Outer, Inner, Last} referring to pairs of terms in the factors (x +a)(x +b). The x terms are the First terms. The Outer terms are the first x and b. The Inner terms are "a" and the second x. The Last terms are "a" and "b". You are to form the sum of those pairs of terms to find the product of the binomials.
Given (-4,9) (-8,9),(-9,7,(-9,4)
...
To Find : plot the point and draw quadrilateral
Solution:
(-4,9)
go 4 left of origin and then go 9 up
(-8,9)
go 8 left of origin and then go 8 up
(-9,7)
go 9 left of origin and then go 7 up
(-9,4)
go 9 left of origin and then go join (-4,9) with (-8,9) and (-9,4) 4 up
join (-9,7) with (-8,9) and (-9,4)
Quadrilateral is constructed
Answer:
and 
Step-by-step explanation:
Given

Required
Find x and y
In the second equation. Assume that:

Substitute
in the first equation


Collect like terms


Multiply through by 5


Solve for x

Substitute this value of x in 





So first find the area
area=legnth times width
area=5/6 times 1/6
5/6 times 1/6=5/36
area=5/36 square units
tile=side legnth 1/6
area of tile=legnth times width or legnth times legnth
1/6 times 1/6=1/36
we must find how many times 1/36 goes into 5/36
divide 5/36 by 1/36
5/36 divided by 1/36=5/36 times 36/1=5/1 times 36/36=5/1 times 1=5
the answer is 5 unit squares needed to tile
