Answer:
The answer is D. I will be writing this because I have to have a certain amount of words
40 = n-.40n
40 =n(1-.4)
40 = n(.6
divide by .6 on each side
40/.6 =n
n=66 2/3
Answer:
C
Step-by-step explanation:
Rectangle: 8*5=40
Triangle 1: (3*5)/2=7.5
Triangle 2: (3*5)/2=7.5
Trapezoid : 40+7.5+7.5=55

To convert from cm to inch divide by 2.54. 75/2.54= 29.5276...
Rounded to the nearest hundredth: 29.53 inches.
Step-by-step explanation:
Answer:
f(4) = 22
Step-by-step explanation:
I think that you type wrongly.
we have f(1) = -5
and f(n) = f(n-1) + 9
Find f(4)
Then
with n= 2 we have f(2) = f(1) + 9 = - 5+ 9= 4
with n= 3 we have f(3) = f(2) + 9 = 4 + 9= 13
and finally with n= 4 we find f(4) = f(3) + 9 = 13+ 9= 22
So f(4) = 22
Hope you understand.
