X=5,2
x^2-6x+8=x-2
x^2-7x+10
(factor)
(what multiplies to be 10 and adds to be -7)
(x-5)(x-2)
(put each equation equal to zero)
0=x-5 x-2=0
x=5,2
Answer:
John needs 217 tiles.
Rate of change is 1.9 tiles per square foot
Step-by-step explanation:
Hallway area=3•38=114 ft²
Rate of change=190/100=1.9 tiles/ft²
Tile total=
T=area•rate
=114•1.9
T=216.6
(Round up because tiles are sold as whole units)
Total tiles=217
