The equation that can be ued to solve for the width of the rectangular frame is 2x² + 14x - 40 = 0.

<h3>What is the equation that can be used to solve for the width?</h3>

A rectangle is a 2-dimensional quadrilateral with four right angles.

Area of a rectangle = length x width

(2x + 4) x (2x + 10) = 120

Expand the brackets

4x² + 20x + 8x + 40 = 120

Add similar terms

4x² +28x + 40 = 120

4x² +28x - 80 = 0

Divide through by 2

2x² + 14x - 40 = 0

To find the length of the light pole you'll have to use the sine ratio.

sin 30 = x/43
43 (sin 30) = x
21.5 = x

Hope this helps :)

Which number line shows the solution set for |y-9| &lt;12
RUDIKE [14]

Answer:

Option c

y\geq-3 or y \leq 21

Step-by-step explanation:

The absolute value is a function that transforms any value x into a positive number.

Therefore, for the function f(x) = |x|  x> 0 for all real numbers.

Then the inequation:

|y-9| \leq 12 has two cases

(y-9)    if y \geq 9  (i)

-(y-9)    if y < 9 (ii)

We solve the case (i)

y \leq 9 + 12\\y\leq21

We solve the case (ii)

-y +9 \leq 12\\-y \leq 12-9\\y \geq -3

Then the solution is:

y\geq-3 or y \leq 21
