Answer:  The required factored form of the given expression is (x-6)(2y+5).

Step-by-step explanation:  We are given to factorize the following expression :

E=2xy+5x-12y-30~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following property :

a(b+c)+d(b+c)=(a+d)(b+c).

From expression (i), we have

E\\\\=2xy+5x-12y-30\\\\=x(2y+5)-6(2y+5)\\\\=(x-6)(2y+5).

Thus, the required factored form of the given expression is (x-6)(2y+5).

Someone told me the answer was 39?? Is this true? Why ? please help.
Ira Lisetskai [31]
The problem has the equation:

f(x) = (3) ^ (x/2)

In order to get the average increase in the number of flowers being pollinated from day 4 to day 10, then we need to use the equation substituting x with 4 to 10

f(4) = 9
f(5) = 12.59
f(6) = 27
f(7) = 46.77
f(8) = 81
f(9) = 140.30
f(10) = 243

Then add all the values and divide it by 7
 = 559.66 / 7
= 79.95

So the correct answer is 79.95

Omar has 3 1/14 cups of dough to make dumplings.If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar
Bumek [7]

Answer:

Omar can make 16 dumplings with some dough to spare

Step-by-step explanation:

you should convert each value to have the same denominator to make the equation easier

3 and 1/14 cups is the same as 43/14 cups of dough

so the total 43/14 needs to be divided by 3/16

43/14 divided by 3/16 = 43/14 * 16/3

=688/42 = 16.3809...

so Omar can make 16 dumplings with some dough to spare
