Hi
I belive you add the top side (4) plus the bottom side (9.5) witch would equal 13.5 times the hieght (3) equals 40.5 divided by 2 equals 20.25. the area is 20.25ft squared
another way to do it
4+9.5= 13.5
13.5×3= 40.5
40.5÷2= 20.25ft
Answer:
Step-by-step explanation:
western beach: y = -2x + 100
dunes beach : y = 5x + 20
set the equations equal to each other
-2x + 100 = 5x + 20
100 - 20 = 7x
80 = 7x
80/7 = x
x ~ 11.43 years
53= -19z+5+7z
53= -12z+5 (combine -19z and 7z)
48= -12z. ( subract 5 on both sides)
-4=z. (divide by -12 both sides)
