The expression 9+5 is equivalent.
No 2x5 does not =15. 2x5=10 ya big dummy
which expression is equivalent to (3 x 10^3) (5 x 10 ^5) sorry that is what i ment
3/5 = .6
they are telling u that X=5, so plug in a 5 anywhere there is an X, so now is 52 x 2x5= 5x5=25 , so now is: 25x(2x5), 2x5=10, so now is 25x10=250 ,so the answer is : x2x (2x) = 52x(2x)=52x(2x5)=25x2x5=250
