Factorize x²+7x+12 ===> (x+3)(x+4)

Factorize x²-3x-28 ===> (x-7)(x+4)

4x + 12 can be written====> 4(x+3)

Then the question could be written as follows:

 [(x+3)(x+4) / (x-7)(x+4) ] / 4(x+3) = [(x+3)(x+4) / (x-7)(x+4) ].[4(x+30]
After simplification you get 1 / 4(x-7)

Of the 120 apartments in a building, 75 have been scheduled to receive new carpet. What fraction of the apartments have not been
Ilia_Sergeevich [38]

Hello!

To find the fraction of the apartments that have not been scheduled to receive new carpet, we need first need find the number of apartments not receiving new carpet, by subtracting the total amount of apartments, by the 75 that have been scheduled.

120 - 75 = 45 apartments

Next, we need to create a fraction. Since 45 out of 120 apartments not are scheduled to get new carpeting, the fraction of these values is 45/120. This can be reduced to 3/8.

Therefore, your final answer is 45/120, simplified to 3/8.

Alex Ar [27]
An orange ... o grams = ?
a pineapple ... p = 7 * o
                        p = 870 grams + o

If you would like to know what is the total weight in grams for the pineapple and orange, you can calculate this using the following steps:

7 * o = 870 + o
7 * o - o = 870
6 * o = 870      /6
o = 870 / 6
o = 145 grams

p = 7 * o = 7 * 145 grams = 1015 grams

Result: A pineapple weights 1015 grams and an orange 145 grams.
