5x-2x=9
three. 1x 18 2x9 3x6
(2x9)/8=18/8=9/4
As a product of its prime factors: 2*3*3 = 18
5x7 - 2x9 + 5x or written properly, -2x9 + 5x7 + 5x
72 i guess!
7x9 is the multiplication fact that can be found using the arrays 2x9 and 5x9.
18
There are no prime factors in that equation.
9
2x9=18
lxb= area 2(l+b)=perimeter take sides 6 and 3 6x3=18 2(6+3)= 2x9=18 hence proved
