(X-5)(X+4)=0 so X-5=0 -----X=5 and X=4=0 so X=-4 it factors to (X-5)(X+4) so X=5,-4
5+x=x+5 is an example of the commutative property of addition.
(x + 7)2 = 5 x + 7 = ±√5 x + 7 - 7 = -7 ± √5 x = -7 ± √5
555 x 5 x 5 x 5 x 5 is five 5's multiplied by each other; when writing an exponent, use the form Bx, where 'B' is the base(the number being multiplied by itself), and 'x' is the exponent(how many times the base is being multiplied). Here, it would thus be written as 55.
If: 2x = x+5 Then: x = 5
It is 200000000000000001000000.
20 sextillion
20 sextillion or 20000 trillion depending on where you are from
this number s pronounced as twenty sextillion
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 78,125
5 to the tenth power would be 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5 X 5, or 9,765,625.
5 x 5 x 5 x 5 x 5 = 3,125
5x5x5x5x5x5=15,625.
(x-5) is the same as x-5
The twelve is an exponent and the five is the base. All you do is 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 or five multiplied by itself 12 times.
(x^2 - 25)/(x + 5) = [(x - 5)(x + 5)]/(x + 5) = x - 5
