Answer:
3x^2+5x+1
Step-by-step explanation:
(x^2 + 3x + 1) + (2x^2 + 2x)
Combine like terms
x^2 + 2x^2 + 3x +2x +1
3x^2+5x+1
You just need to divide the given numbers to get the answer.
For example,
Question: Chad reads 30 pages in 3 hours. How many pages can he read in 1 hour.
Answer: 30/3=10
Therefore, Chad reads 10 pages in 1 hour.

Answer:
so natural numbers are numbers which of 1... to positive infinity
But when we talk about integers are both positive or negative numbers
either from -1 and above or +1 infinity and above
Answer:
85
Step-by-step explanation:
1/2(6x5) = 15
15x4 = 60
5x5= 25
25 + 60 = 85
Answer: 6units
Step-by-step explanation:
Since it is a regular polygon, and it has 3 equal sides it means the polygon is a quadrilateral.
From the diagram,
5 - 2x = -4x + 9 ( side of quadrilateral )
Solving for x in the equation
-2x + 4x = 9 - 5 ( collection of like terms in simple linear equation )
2x = 4
Divide through by the coefficient of x which is 2
x = 2.
Therefore, the perimeter of the polygon which equals to the total length of the polygon is
Perimeter = 2 + 2 + 2
= 6units
