Answer:
Area of the rectangle is given by:
where
A is the area of the rectangle
l is the length of the rectangle
w is the width of the rectangle respectively.
As per the given statement:
Area of the rectangle(A) = 
square meters
length of the rectangle(l) = x+8
Substitute these in the given formula we have;
or
Divide both sides by x+8 we have;
meters.
Therefore, the expression represents the width of the rectangle is x-9 meters
Joe wants to build a fence for his dog Charlie.
The lengths of the perimeter of the rectangle that he plans to surround with fence are as follows:
10 feet + 15 feet + 10 feet + 15 +feet.
The total perimeter area of a rectangle is worked out as follows:
10 + 15 + 10 + 15 = 50
Therefore Joe needs 50 feet of fencing to totally surround the rectangle with fence.

⇒ Option A is correct.
Answer:
the graph opens upward
the graph is steeper then the graph of f(x) = x2
and the graph is the same as the graph of f(x)=6x2 + 12x -3
Step-by-step explanation:
Answer:
1
Step-by-step explanation:
S = {,10,11,12,13,14,15,16,17,18,19,}
n(s) = 10
P(a) = n(a) / n(s)
= 10 / 10
= 1 / 1
= 1
