First of all, let's find the water tank total amount
according to the exercice, there were 2 L (L =liters) of water at 6 am (6hours after midnight ).
Consider T as total amount of water
so we have
T=(6×2)+2=14 as we already know it's emptying 2 L per hour

y=14-2x , here is the equation !

6x^2-4xy-15xy+10y^2 factor by grouping
PtichkaEL [24]

Best Answer
We will need to split the middle term and use the grouping method. To do this multiply the coefficient of the first term (6) against the coefficient of the last term (10):

6 * 10 = 60
Factors of 60 = +-(1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60)

From the list of factors find two numbers that when added together give -19 and when multiplied together give 60. -15 and -4 added together give -19 and multiplied together give 60 so split the middle term by rewriting these values back into the expression:

6x^2 - 15xy - 4xy + 10y^2

Now use the grouping method, take out the highest common factor between the two sets of terms:

3x(2x - 5y) - 2y(2x - 5y)

Group the outside terms:

(3x - 2y)(2x - 5y)


Answers
6 = -3*-2
10 = 5*2
5*3+2*2=19
thus
(2y-3x)(5y-2x)

so, im t trying to find the original price and sale price of a book for example and the amount of discount is 2.80 dollars and t
aliya0001 [1]

Okay, so since the discount is 60% of the price and it comes out to $2.8, we are going to form the following expression, where x is the original price.

60% of x = 2.8

Simply means: 60/100 * x = 2.8

You solve for x, which comes out to $4, which is your original price.
