Answer
30
steps
area of trapizium is a+b/2 * h.
we have a=14, h=15, area=330 and we need to find b
so, 14+b/2 * 15=330
we divide 15 on both sides so 14+b/2=22
we multiply 2 on both sides so 14+b=44
b=44-14
b=30
Answer:
what is it asking??? I'm so confused!!!? ://
-4(3)=-12
-4(6)=-24
-12+(-24)=-36
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.
