Solve EXACTLY like the example attached.
Transcribed Image Text:Write the perimeter in standard form.
7x²-8
dx+5
X+4
3x² - 4x
12x2
-5x+8
Transcribed Image Text:he area and perimeter of the figure? Assume there is a right angle at each vertex.
2x + 15
15x + 10
1
9x+2
2
8x+15
10x + 30
6x+8
Length = (10x +30) - (2x+15)
=
+
=
Perimeter = all sidelengths added
2x + 15
9x + 2
8x +15
10x +30-2x-15
8x + 15
Perimeter =
8 + عام
(ox +30
15x + 10
50x+80
if x=5 Total Area = 78 (5) ² + 399 (5) + 270
= 4215 sq. units
= 50 (5) +80= 330 lenits
