Assuming that all tiles must stay whole it would be:
1×54
2×27
3×18
6×9
5>x because you can subtract 5 from both sides and 3x from both sides
Answer:
9:30 she finishes
Step-by-step explanation:
815 plus 75 is 890
there are 60 minutes in one hour
890-60 is 830
add 100 to represent another Hour
830 plus 100 is 930
9:30
therefore, it is 9:30
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
