Answer:
The required formula is:
Step-by-step explanation:
The total number of squares of the the first term = 4
The total number of squares of the the second term = 7
The total number of squares of the the third term = 10
so,
Finding the common difference d
As the common difference 'd' is same, it means the sequence is in arithmetic.
So
If the initial term of an arithmetic progression is and the common difference of successive members is d, then the nth term of the sequence is given by:
Therefore, the required formula is:
Answer:
4
Step-by-step explanation:
Let x=papers on Saturday and y=papers on Sunday
First make equations for the information given to you
x+y=52 (total papers) and y= x+8 (he sold 8 more on Sunday)
then since you know y=x+8 then substitute it in the other equation like so
x+(x+8)=52 which means 2x+8=52 which means 2x=44 and therefore x=22
the problem however asks for sunday and not saturday, so solve for y now
y=x+8 which means y=22+8 which means y=30
He sold 30 papers on Sunday
Answer:
A = bh
Step-by-step explanation:
The area of a triangle is defined as half the product of its base by its height.
A = bh
If you do not know the height but you know the length of the three sides of the triangle you can use Heron's formula to find the area
If the lengths of the sides are a, b, c then the area is
