What are the diameters of the painting?<br> Easy!!!
zalisa [80]

x = 10.22 in

Solution:

Width of the figure = x in

Length of the figure = (2x + 5) in

Area of the figure = 260 in²

<u>To find the value of x:</u>

<em>Area of the figure = length × width</em>

length × width = 260

(2x + 5) × x = 260

2x^2+5x=260

Subtract 260 from both sides of the equation.

2x^2+5x-260=0

Factor the above quadratic expression.

Quadratic equation formula:

$x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}

$x=\frac{-5 \pm \sqrt{5^{2}-4 \cdot 2(-260)}}{2 \cdot 2}

$x=\frac{-5 \pm \sqrt{2105}}{4}

$x=\frac{-5+\sqrt{2105}}{4}, \  x=\frac{-5-\sqrt{2105}}{4}

x = 10.22,   x = –12.72006

Dimension of the figure cannot be measured in negative terms.

Hence x = 10.22 in.

Line m passes through points (3, 15) and (10,9). Line n passes through points (2,9) and (9, 3). Are line m and line n parallel p
enot [183]

Answer: they are parallel

Step-by-step explanation:

find slope of line m:

Use y2-y1/x2-x1

your m equation --> 9-15/10-3 which makes the slope of m = -6/7

find slope of line n:

Use y2-y1/x2-x1

your n equation --> 3-9/9-2 which makes the slope of n = -6/7

The slopes are the same, therefore line m and line n are parallel.
