the bottom of the spinner is not flat.
step-by-step explanation:
6(h+1)/2=a
a=area
its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.
86
find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2
you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
