The floor of a rectangular room will be tiled with square tiles that measure 3 inches on each side. The room is 109 inches long and 103 inches wide. ...
Answers
1)
x= the width
2x=the length
x-3= the height
V=x*2x*(x-3)=2x^3-6x²
2)
16-8=8
24-16=8
32-28=8
difference=8
answer D
3)
a) if you put the squares side by side horizontaly you will need 37*34=1258 squares (for a perfect job)
b) or 109*103/9≈1248 squares (cutting squares)
L=2W
heigt is 3 less than width
H=W-3
if W=x
V=??
V=LWH
W=x
L=2x
H=x-3
V=(2x)(x)(x-3)
V=(2x^2)(x-3)
V=2x^3-6x^2
common difference is the nth term minus the n-1 term
basically a term minus the one before it

how many tiles
find area of room
area of room=109*103=11227
area of tile=3^2 since it is asquare or 9
areaof1tile times how many tiles=areaofroom
9*howmany=11227
divide both sids by 9
how many=1247.44444
round up so you have enough (since you can't buy 0.4444 tiles)
how many=1248
1248 tiles

Answer:
D
Step-by-step explanation:
The width of the rectangle is 4 ft, since the base of the podium is 6ft in total, the remaining length for the two triangles would be 2 ft.
2/2 = 1
The base of each triangle is 1 ft.
This means the area of the triangles would be 2(0.5 x 2 x 1) while the area of the rectangle would be 4 x 3.
4 x 3 = 12
2(0.5 x 2 x 1) = 2
12 + 2 = 14
