Simplify the rational expression:<br> x^2+13x+42/x^2+15x+56
ANTONII [103]

Answer:

x+6/x+8

Step-by-step explanation:

First, factor out each of the expressions. You will use the AM method, where the last term is the factors multiplied together, and the middle term is the two added together. For the top, you would get (x+7) and (x+6) as your factors, and for the bottom you'd get (x+7) and (x+8). Based off of that, you can simplify your answer. The two (x+7)'s can cancel out, leaving you with a (x+6) over (x+8) as your answer.

Danny Henry made a waffle on his six-inch-diameter circular griddle using batter containing a half a cup of flour. Using the sam
Mekhanik [1.2K]

Answer:

He'll need 288 cups to make a waffle on his 24 foot diameter circular griddle.

Step-by-step explanation:

In order to find out how much batter Danny needs we first need to compute the area of the first pans, since it is a circular pan their area is given by A = 2*pi*r. So we have:

Area of the first pan = 2*pi*(6/2) = 18.84 square inches

Area of the second pan = 2*pi*(24/2) = 75.36 square foots

We now need to convert these values to be in the same unit, we'll convert from square foots to square inches:

Area of the second pan = 75.36 * (12)^2 = 10851.84 square inches

We can now use a proportion knowing that the batter and the thickness of the waffles are the same. If 0.5 cup of flour can make a waffle on 18.84 square inches then x cup of flour can make a waffle on 10851.85 square inches. Writing this in a mathematical form, we have:

0.5/x = 18.84/10851.84

18.84x = 0.5*10851.85

x = 10851.85*0.5/18.84 =288 cups
