Answer:
19x-1/3
Step-by-step explanation:
it is the right answer we have to take lcm for this by taking only lcm we can solve it..
Change the numbers into improper fractions then subtract
The GCF is only 12 because 16 can't multiply a number that gives you 48 only 12.
Take half of the coefficient of x (which is 2/5) and square it:
[ (1/2)(2/5) ]^2 = (1/5)^2 = 1/25, or 0.04
Thus, to rewrite x^2 + (2/5)x to include a perfect square trinomial,
x^2 + (2/5)x = x^2 + (2/5)x + (1/5)^2 - (1/5)^2, or
(x+1/5)^2 - (1/5)^2, or (x + 1/5)^2 - 1/25
If you treat multiplication as repeated a<span>ddition, then y</span>es, Juan is correct. Only equal groups can be multiplied.
