S= kayas sister A= kaylas age
S-4=A
Answer:
See below.
Step-by-step explanation:
So we have the two functions:
And we want to find f(x) + g(x).
So, substitute:
Combine like terms:
Simplify:
So:
The width of the border will be about 2.5 feet.
The area of the rug is 9 by 7. Let's call the width of the border x. Therefore, the length of the rug will switch to 9 + 2x. The border is on both sides of it, so we add on 2x. Then, the width is 7 + 2x.
The area of the room is therefore: (9 + 2x)(7+ 2x).
We know the area of the room, so we can write and solve the following equation.
(9 + 2x)(7 + 2x) = 167
4x^2 + 32x + 63 = 167
4x^2 + 32x - 107 = 0
At this point, use the quadratic formula and x will equal about 2.5.
Answer:
where is the graph
Step-by-step explanation:
I need the graph to do the problem
I believe the answer would be b^4.
Explanation:
Use Quotient Rule: x^a/x^b=x^a-b
b^10-6
Then Simplify 10-6 to 4
b^4
