log(x–4)+log(x+3)=2logx
Answer:
Equation is:
Length in yards is 16 yards.
Step-by-step explanation:
Let 'L' represent length in feet and 'y' in yards.
Given:
Length of the waterslide is,
Length in feet is three time its length in yards. Therefore,
Length in feet = 3 Length in yards.
∴
Dividing both sides by 3, we get:
Now, plug in 48 for 'L' and solve for 'y'. This gives,
Therefore, the length of the waterslide of length 48 feet in yards is 16 yards.

Step-by-step explanation:
The general form of equation of a circle is given by :-
, where r is radius and (a,b) is the center of the circle.
The given equation of circle:
Taking square root on both sides, we get
Hence, the length of the radius for this circle=

The difference of a number q and 8 is q-8.
It is required to write thedifference of a number q and 8.
What is algebra?
A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.
Given that:
considering the word "difference" means subtraction, so to subtract 8 from q.
the difference of a number q and 8 is
q-8.
Therefore, the difference of a number q and 8 is q-8.

Answer:
is the expression with the value of 15 when n = 7
Step-by-step explanation:
To find the expression whose value is 15, substitute the value of n = 7 in each given expression.
Expression 1:
Substitute the value of n & simplify,
Since the value of the expression is 8 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 2:
Substituting the value of n & simplify,
Since the value of the expression is 16 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 3:
Substituting the value of n & simplify,
Since the value of the expression is 14 which is not equal 15.
Hence expression does not have value of 15 when n = 7.
Expression 4:
Substituting the value of n & simplify,
Since the value of the expression is 15 which is equal 15.
Hence expression has the value of 15 when n = 7.
