A. Rice costs $1.33 per kilogram. How much will 1.3 kg of rice cost?

Katen [24]

A. If a rice costs $1.33 per kilogram, then 1.3 kg will cost 1.33 * 1.3 = 1.729. We can round it $1.73.

B. If a milk costs $0.71 per liter, with $3.00 you can buy 3 / 0.71 = 4.22 liters (after rounding to the hundredth).

C. In (A) we have cost of standard amount and an information how many of rice we want to buy. We find it by multiplying. In (B) we have cost of standard amount and an information about how much money do we have. We find it by dividing.

Factor completely h^3+2h^2-9h-18

guapka [62]

Step 1: Group this into two groups:

$h^3 + 2h^2-9h-18=(h^3 + 2h^2)+(-9h-18)$

When you do that, be sure to group the "–" into the group with the 9 and make sure there's "+" between the groups.

Step 2: Factor out the GCF from both individual groups:

$(h^3 + 2h^2)+(-9h-18) = h^2 (h+2) -9(h+2)$

Step 3: Notice both groups have that (h+2)? That's a new GCF between the two groups, so factor that out:

$h^2 (h+2) -9(h+2) = (h+2)(h^2-9)$

Step 4: That $(h^2-9)$ piece can be factored further, since it's a difference of squares:

$(h+2)(h^2-9) = (h+2)(h+3)(h-3)$

Now it's factored.
