x2-20x+100 = (x-10)(x-10) when factored
((3 x 100) + (5 x 10) + (4 x 1)) + ((7 x 100) + (8 x 10) + (2 x 1))
55.505 = (5 x 10) + (5 x 1) . (5/10) + (0/100) + (5/1000)
x + 50 = 2x + 100 50 = 2x+100-x 50 = x + 100 50-100=x -50=x -50+50=0 -100+100=0 it is zero
% rate:= (10/10) x 100%= 1 x 100%= 100%
write a numerals of 8 x 100000 + 4 x 100 + 10
x2-20x+100 = (x-10)(x-10) when factored
(x - 10)(x - 10)
x=10
If that first term is x2, the answer is (x - 10)(x - 10) or (x - 10)2
10x+10y+100 There is a common 10 in each number. 10(x+y+10)
X=65
100 + 30 + 5 = 135 or 10 x (10 + 3 + 0.5) = 10 x 13.5 = 135
5370
These are Roman numbers: C=100, X=10, V=5, II=2, thus 100+10+5+2 will be 117 or CXVII.
90 + 10% = 90 x (1 + (10/100)) = 90 x 1.1 = 99
