Step-by-step explanation:
Answer:
12 feet
Step-by-step explanation:
Two buildings have the same total number of heights
The first building has 6 floors each with height h
The second building has a ground floor of 36 feet and 3 other floors each
Since both buildings have the same height then
Height of first building= height of second building
The first step is to calculate the height of the first building
Height of first building = 6h
The height of the second building is
36 + 3h
Therefore the height of each floors can be calculated as follows
6h= 36 + 3h
Collect the like terms
6h-3h = 36
3h= 36
h= 36/3
h= 12
Hence the height of each floors is 12 feet
Answer:

such that
1≤x≤7
.
answer is 77
Step-by-step explanation:
Answer: x ≥ 7
Step-by-step explanation:
You have to square both sides of the equation. You can manipulate an equation or function any way imaginable as long as it is done equally and helps the problem become easier. If we square this, the radical will cancel and we will get two trinomials equal to each other.

We can see the two expressions are exactly equal to each other. All real numbers are solutions, besides a few. These few are when the radical is equal to a negative number. So lets set up an inequality stating that the radical must be greater than or equal to 0.
