Answer:
Step-by-step explanation:
Perimeter of triangle = 4x - 3 + x + 9 + 8
= <u>4x + x</u> -<u> 3 + 9 + 8</u>
= 5x + 14
Area = 

To find the area of a polygon you have to write the formula of it which is area= 1/2 x perimeter x apothem . hope this helps
The equation that best models this situation would be: y=40+30x
Answer:
y = 4
Step-by-step explanation:
This is a never changing equation that sets y as 4 no matter what, so it's a horizontal line, a slope of zero.
1) 90-27= 63
2)90divide by 3= 30
3)90-40=50
50 divide by 2=25
4)d and f= 57
e=82
5) 74+53=127
180-127=54
6) i=90-64
=26
h=90 (straight line)
