Answer:
The perimeter of the square is 16 √ 5
The area of the square is 8√5
Step-by-step explanation:
To solve this you first need to solve 4√5 which is 8.94. This made the perimeter 35.76 which is equaled to 16√5. The area is 17.88 which is the same as 8√5.
Hi!
<u>Explanation: </u><u><em>This question is super super easy! You had to used PEMDAS for order of operations. First multiply by 5*4=20, from left to right. Then 32+20=52 and it gave us the answer is 52 is the right answer. Hope this helps! And thank you for posting at here on Brainly. And have a great day. -Charlie </em></u>
The first term of an arithmetic sequence is 1.2 with a common difference of 8.
<h3>What is a sequence?</h3>
It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
We have:
Tenth term of an arithmetic sequence = 73.2 or
a+(10-1)d = 73.2 ....(1)
Second term of an arithmetic sequence = 9.2 or
a+(2-1)d = 9.2 .....(2)
Where a is the first term and d is a common difference.
Solving equations (1) and (2)
From the equation (2) put the value of d in the equation (1), we get:
a+9(9.2-a) = 73.2
a+82.8 - 9a = 73.2
-8a = -9.6
a = 1.2
Thus, the first term of an arithmetic sequence is 1.2 with a common difference 8.
