Answer:
Step-by-step explanation:
-3 = -x - 2
the equation is a bit hard to read in your questions but if that is the correct equation then the slope is -1
Answer: D
Step-by-step explanation:

To find the area of the trapezoid, we only need the quantities a1 (long base), a2(short base) and h(height).
Area=(1/2)(a1+a2)*h
=(1/2)(9.9+4.7)(5.6)
=40.88 mm ²
Not sure what's expected to give for "type". Perhaps trapezoid or trapezium.
Change 25% to .25. Multiply .25 by 50 to get 12.5. Subtract 12.5 from 50 to get $37.50
