X shortest piece
X+6 middle piece
X+8 longest piece
Add them
3x+14=56
3x=42
X=42/3=14
Answer:
y=mx+b is the slope intercept form.
Step-by-step explanation:
m is the slope (how the line is moving across the graph)
b is y-intercept (where the line crosses the y axis)

Answer:
64 + 28 = 92
Step-by-step explanation:
Split the figure in half creating two triangles and a square.
length and width for the square would be 8ft and 8ft. Multiply both for 64 to be the area.
7ft and 4ft are the height and base for the triangles.
In this case, just multiple 7 and 4 because normally you would need to divide the product by 2 however since there are two triangles it negates the step.
The measure of one of its angles is 150°. The correct option is D.
<h3>How to calculate the angle?</h3>
The value of angles in a polygon is calculated by using the formula:
= (n - 2) × 180°
where n *+ number of sides
This will be illustrated as:
= (n - 2) × 180°
= (12 - 2) × 180°
= 10 × 180°
= 1800°
Since it has 12 sides, the value of each angle will be:
= Total angle / Total sides
= 1800° / 12
= 150°
The angle is 150°.
