The n two number are n and n+7. The two numbers are relatively prime because 7 is prime and doesn't divide 60. So we get n(n+7)=60. Guess and check tells us the two numbers are 5 and 12.

Factor 6y 2 - 48 + 42y

<h2>Answer:</h2>

The factorization of the given expression is given by:

           6y^2-48+42y=6(y-1)(y+8)

<h2>Step-by-step explanation:</h2>

To factor a polynomial means to express it as a product of the rational factor of the given expression.

The quadratic expression in terms of the variable y is given by:

6y^2-48+42y

It has three terms such that all the three terms are a multiple of 6 , hence we take out common 6 from each term to get the expression as:

6y^2-48+42y=6(y^2-8+7y)\\\\i.e.\\\\6y^2-48+42y=6(y^2+8y-y-8)\\\\i.e.\\\\6y^2-48+42y=6(y(y+8)-1(y+8))\\\\i.e.\\\\6y^2-48+42y=6(y-1)(y+8)

Elimination Method<br> 2x-4y=12 -x+2y=-6
Readme [11.4K]

Answer:

The given system has INFINITE NUMBER OF SOLUTIONS.

Step-by-step explanation:

Here, the given system of equation is given as:

2 x - 4 y = 12   ...  (1)

- x + 2 y = -6   ......  (2)

Now, to use the ELIMINATION METHOD we either need to cancel out x coefficients or the y coefficient.

Now, to cancel out the x- coefficient in both the equations:

Multiply equation (2) with 2 and add with (1), we get:

2 x  - 2x + 4 y - 4 y = 12 - 12  

or, 0 = 0

Hence, the given system has INFINITE NUMBER OF SOLUTIONS.
