Answer:
Step-by-step explanation:
Given: r(x)=3x-1 and s(x)= 2x+1
We have to find
That is to find
first find r (6) and s(6) , then substitute, we get,
r(6)
r(x) = 3x - 1
Put x = 6 , we get
r(6) = 3(6) -1 = 18 - 1 = 17
s(6)
s(x) = 2x + 1
Put x = 6 , we get
s(6) = 2(6) + 1 = 12 + 1 = 13
Thus,
Answer:
$346.50.
Step-by-step explanation:
Imagine that the 9*9 square on the left is a part of the floor then:
The area = area of a trapezium - 9^2.
So the area of the dining area = 1/2 * (31 + 21) * 12 - 9^2
= 231 ft^2.
So they should plan to spend 231 * 1.5 = $346.50.
