A)
It looks like the [irregular] hexagon has 3 rectangles and 2 triangles within it.
So let's exclude the triangular corners on bottom left and top right for now.
First we have a large rectangle covering most of the upper left of the polygon. 20 ft × 7 ft = 140 sq.ft.
Now we have a rectangle on the bottom right. The width is 11 ft, so take the 7 away from that, 4 ft. × 14 ft. on bottom. 4 ft × 14 ft = 56 sq.ft.
The last small rectangle fits on the right between the 2 other rectangles. It is 24-20 on top/bottom × 7-6 right/left. 4 ft × 1 ft = 4 sq.ft.
Now for the triangles: bottom left is 11-7 × 24-14 = 4 ft × 10 ft. 1/2bh = 1/2×10×4 = 20 sq.ft.
Top right is 24-20 × 11-5 = 4 ft × 6 ft. 1/2bh = 1/2×4×6 = 12 sq.ft.
B)
Add them all together for the total area (A):
A = 140 + 56 + 4 + 20 + 12 = 140+60+32
= 232 sq.ft.
Hope that explains it well enough! ;)
Your answer should be x < 0 or x > 4.

Answer:
30
Step-by-step explanation:
2400 + 100x = 2200 + 120x
2400 - 2200 = 120x - 100x
200 = 20x
200/20 = x
10 = x <== they would have to sell 10 systems

the equation of a line in point- slope form is
y = mx + c ( m is the slope and c the y-intercept
thus y = 4x + 3 ← in slope-intercept form
the equation of a line in point- slope form is
y - b = m(x - a ) ( m is slope and (a, b ) a point on the line )
thus y - 3 = 4 ( x - 0 ) or y - 3 = 4x ← in point- slope form
the equation of a line in standard form is
Ax + By = C ( a is a positive integer and B, C are integers
rearrange y - 3 = 4x into this form
4x - y = - 3 ← in standard form
(12)
y = - 2x - 1 ← in slope-intercept form
y + 1 = - 2x ← in point- slope form
2x + y = - 1 ← in standard form
