126 units
Step-by-step explanation:
the lateral area of a regular pyramid with a square base of 126 units has a slant height of 9 units and base side lengths of 7 units.
Answer:
The answer is (x + 4)² = 0
hope that helps
----------------------------------------------------------
Define x :
----------------------------------------------------------
Let one of the number be x. The other number is x + 2.
----------------------------------------------------------
Construction Equation :
----------------------------------------------------------
The sum of the square of the two number is 202.
----------------------------------------------------------
Solve for x :
----------------------------------------------------------
x = -11 is rejected, since it only want positive integer.
----------------------------------------------------------
Find the two numbers :
----------------------------------------------------------
x = 9.
x + 3 = 11
----------------------------------------------------------
Answer: The numbers are 9 and 11.----------------------------------------------------------
You could have ANY rule you want. Just substitute for and for but MAKE SURE THAT ONCE YOU SIMPLIFY IT, IT IS TRUE. Lets start making some equations!
How about:
If we substitute into it, we find it works.
How about:
By the way, if you substitute y and x into the equation above, you will find they also work.
Thank you, and I hope this helped.

Let us assume that the number of days she practiced the piano to be "d"
Since she practiced 2/3 hours a day, the total number of hours would be: 2/3*d
Now we are given the total number of hours during summer that she practiced be be equal to 32/23
So we equate 2/3 * d to 32/23 to find d
2/3*d = 32/23
d = (32/23)/ (2/3)
d = (32/23) * (3/2)
d = 48/23 hours
The equation that can be used to find the number of days that she practiced piano during the summer is 2/3*d = 32/23
