For (h+g)(x) you just add the two functions:
(h+g)(x) = 4x + 2x^2
For (h•g)(x) you multiply them:
(h•g)(x) = 4x • 2x^2 = 8x^3
For (h-g)(x) you subtract them:
(h-g)(x) = 4x - 2x^2
For (h-g)(-2) you sub -2 into the equation we just created:
(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16
Yes he does because the final price would be $7.95.
Answer:
(x + y)^5.
Step-by-step explanation:
The (r+1)th term of (x + y)^n = nCr x^n-r y^r
Compare this with 10x^3 y^2 we get
nCr = 10 , n-r = 3 and r = 2 giving n = 3+2 = 5
5C2 = 10.
So the answer is (x + y)^5.
Answer:
Total length of string required in yards 
yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to 
feet
In the party total number of balloon used is equal to 
balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
feet
1 feet is equal to 13 yards
Total length of string required in yards 
yards
