Answer:
area= 7725
Step-by-step explanation:
A = 75((125+81)/2) A = 75(206/2) A = 75(103) A = 7725 The area is 7725 square feet
X=6
g(f(x))=g(f(18))
=g(5/6*18 +5)
=g(20)
=(5*20)+6
=106
We will find that the ratio of 3 less than k to 2 more than k is:
(k - 3):(k + 2)
The ratio between two numbers A and B can be written as:
A:B
This is the ratio of A to B
and
B:A
Is the ratio of B to A.
Then for the ratio of 3 less than k to 2 more than k we have:
"3 less than k" is: k - 3
"2 more than k" is: k+ 2
Then the ratio is:
(k - 3):(k + 2)
