Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:

where it has taken into account the sum of the area of a square and four triangles:

h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:

hence, the surface area is 85cm^2
Answer:
Each of them had $49 at first.
Step-by-step explanation:
Given:
Cedric and Doug each had an equal amount of money.
Let the number of money they had at first be x
Cedric spent = $35
Doug spent = $28
Cedric Money left = 
Doug Money left = 
the ratio of Cedric money to Doug money was 2:3
Hence the expression can be made as;

Now by cross multiplication method we get;

Now we will use distributive property to elaborate the same;

Combining common terms we get;

Using Subtraction property we get;

Hence $49 they each had at first.
I wrote the domain and range in interval notation, not sure if that’s how you’re asked to do it. This is how I was taught to state the domain/range of a graph.
The answer is (9x^8y^3)/2.
