Write a ratio for the following word phrase. Write fractions in lowest terms.42 in. to 6 ft
ollegr [7]
42 feet to 6 feet can be written as both ratio and a fraction:

42:6
42/6

If we look at the fraction, we can clearly see that we can simplify it:

42/6 = 7/1 = 7

So we can write the ratio in its lowest terms as 7:1.

To complete the square, how do you find the value that must be added to the expression to make a perfect square trinomial? What
Molodets [167]
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
