the perimeter of a rectangle is twice the sum of its length and its width. The perimeter is 34 meters and it’s length is 2 meter
-Dominant- [34]

Here is your answer

Let the widht of rectangle be x metres

Then, its length= x+2 metres

Perimeter= 2 (l+b)

=> 34 = 2 (x+2 + x)

=> 34/2 = 2x+2

=> 17= 2x+2

=> 2x= 17-2

=> x = 15/2 metres

Width= 15/2 metres

Length= 15/2 + 2

= 19/2 metres

HOPE IT IS USEFUL

Answer:

-4x^5y^3-3x^4y^3+x^5y^2

Step-by-step explanation:

You need to know this indice rule:

If you multiply two terms with the same base, then add their powers and multiply their coefficients.

(4x^2y+3xy-x^2)(-x^3y^2) : Here we have to multiply each term in the first pair of brackets by the term in the second pair of brackets.

So we can split this into parts:

(4x^2y)(-x^3y^2) +(3xy)(-x^3y^2)+(-x^2)(-x^3y^2)

Now using the rule above expand the brackets:

(4x^2y)(-x^3y^2) = -4x^5y^3 : Notice how y * y^2 =y^3 since y = y^1 so 1 + 2 = 3.

(3xy)(-x^3y^2) = -3x^4y^3

(-x^2)(-x^3y^2) = x^5y^2 : Be careful with negatives, two negatives make a positive.

Now add them all together:

-4x^5y^3-3x^4y^3+x^5y^2

Determine if the equation x^2 + 3y^2= 3 defines y as a function of x
belka [17]

Answer:

y is NOT a function.

Step-by-step explanation:

The equation given to us is:

x² + 3y² = 3

Rearrange the equation:

3y² = 3 - x²

y² = (3 - x²)/3

y² = 1 - (x²)/3

y = ±√(1 - x²/3)

For any equation to be a function, there should be only one output for one input. Which means that for any value of x, there should be only one value of y. However, in this equation, as the underroot gives two values of any terms under it, it shows that if we put any value of x, we'll get 2 values of y. Therefore, y is not a function.
