To estimate, you can round each decimal to the nearest whole number, and then add them up together to get a number close to the real answer.
I hope this helps! :)
Answer:
right triangle
Step-by-step explanation:
A Right triangle is a triangle that has one of its angle as 90°.
Since the triangular shaped tiles has a right angle, the kind of triangle Kevin found will be a right triangle.
A right triangle has two acute angles (angles less than 90°) and a right angle
The pattern is plus 10 for each time
Formula recursive
A_n = A_n -1 + 10
So the next term is 5th
A_5 = A_5 -1 + 10
A_5-1 = A_4 +10
5th = 6+10 = 16
I think you can do it for the next 2 terms.
Answer:
The lateral area is 
Step-by-step explanation:
we know that
The lateral area of a right prism is equal to

where
P is the perimeter of the base of the prism
H is the height of the prism
in this problem we have


substitute

Answer:
Step-by-step explanation:
A solution set is the set of values which satisfy a given inequality. It means, each and every value in the solution set will satisfy the inequality and no other value will satisfy the inequality.
Example:
Solve 2x + 3 ≤ 7, where x is a natural number.
Solution:
2x + 3 ≤ 7
Subtracting 3 from both the sides,
2x ≤ 4
Dividing both sides by 2,
x ≤ 2
Since x is a natural number,
Solution set = {1,2}.
