There are many ways to figure 2.5x2.5. If the decimals confuse you, remove the decimals and you may insert them at the end. 25x25=625.
Remember*: When multiplying vertically, don't insert the decimal under the decimals in the factors:
2.5 Instead, move the decimal two places to the left since there
x2.5 are two decimals (one in each factor)
____ so that the answer is 6.25.
62.5 Not correct.
125 or 9765625.
x - 25 = 38 x - 25 + 25 = 38 + 25 (add 25 to both sides) x = 63
x+25=138 subtract both sides of the equation by 25 (x+25)-25=138-25 simplify x=138-25 x=114
25 x 25 x 25 = 15625
4 x 25 x 27 = (4 x 25) x 27 = 4 x (25 x 27) = (4 x 27) x 25 They all equal 2700.
25 x 6 is 150. 25 x 1= 25 25 x 2= 50 25 x 3= 75 25 x 4= 100 25 x 5= 125 25 x 6= 150
Solve for x. x - 25 = 680 isolate x by adding 25 to both sides. x = 680 + 25 x = 705

x = 25^2 = 25*25 = 625.
( x^2 - 25 ) = ( x + 5 ) ( x - 5 ) <--------------------------
x in x 15 25?
[ x - 25 ] has no solution.
