Answer:

( y^2 +1) ( x^2+1)

Step-by-step explanation:

Step 1 ) Factor out x^2 from the expression

x^2 (y^2+1)+y^2+1

Step 2) Factor out y^2 from the expression

(y^2+1) (x^2+1)

Solution is ( y^2 +1) ( x^2+1)

The graph suggests that the two lines meet at $(3,6)$

If this is true, that point must belong to both lines.

To check this, plug $x=3$ in both equations, and you must get $y=6$ once you simplifiy all the numbers.

In the first equation we have

$5\cdot 3-3y= -3 \iff 3y=15+3\iff 3y=18 \iff y=6$

In the second,

$3+3y=21 \iff 3y=18\iff y=6$

The length of a rectangle is 3 m less than twice the width if the area of the rectangle is 66 5 m² find the dimensions

goblinko [34]

Let the width be x.

Then,Length = ( 2x - 3 ) m

According to the question,

Area of rectangle = 665 m² [ Given ]

Formula: Area of rectangle = Length × Width

$\sf \implies \: length \: \times breadth = 665 \: m {}^{2}$

$\sf\implies \: (2x - 3) \times x = 665$

$\sf \implies \: 2 {x}^{2} - 3x = 665$

$\sf \implies \: {2x}^{2} - 3x - 665 = 0$

By split middle term

$\sf \implies \: 2 {x}^{2} - 38x + 35x - 665 = 0$

$\sf\implies \: 2x(x - 19) + 35(x - 19) = 0$

$\sf \implies \: (2x + 35) = 0 \: or \: (x - 19) = 0$

$\sf \implies \: x = \dfrac{ - 35}{2} \: or \: \: x = 19 \:$

Note: Ignore negative number.

Now,

Width of a rectangle = 19 m

Length of a rectangle = 2x - 3 = 2 × 19 - 3 = 38 - 3 = 35 m
