Determine whether the binomial can be written as a difference of two squares. (a) p9 – 25 (b) a8 – 18 (c) g2 – 36

- "Technically, all of the choices can be written as a difference of squares. Just find the square root of both terms and use the formula.

However, I am going to assume that your problems want to know if the expressions can be written as a difference of two squares, where  and  are either variables with an even exponent or a perfect square, as this is what many instructors are asking for."

- "C.) We can apply it to Choice C, since g has an even exponent and 36 is a perfect square. Applying the formula, we get:

g^2 - 36 = (g + 6)(g - 6)"

(C.)g2 - 36

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
