A(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27

How do i use the decimals 2.47,9.57,and 7.1 to write two different addition facts and two different subtraction facts?
VARVARA [1.3K]

<u>Answers</u>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47


<u>Explanation</u>

A fact family is a group of math facts using the same numbers.  In the case of addition/subtraction, you use three numbers and get four facts.

In this case we are going to write two different addition facts and two different subtraction facts as follows:

2.47,9.57,and 7.1

<em><u>Addition facts</u></em>

2.47 + 7.1 = 9.57

7.1 + 2.47 = 9.57

<em><u>Subtraction</u></em>

9.57 - 2.47 = 7.1

9.57 - 7.1 = 2.47
