Answer:
70 is the answer.
Step-by-step explanation:
180+240= 420
420 divided by 6 is 70
here it is :)
do check properly, I have given step by step instructions:)
do give feedback on my answer, would appreciate it!
<em>Answer:</em>
n²+3
<em>Explanation:</em>
The differences between the terms are not the same, so this is not "linear". Knowing that the sequence may have started with a 1, you can try subtracting the first number with a number to get 1, and use that number to subtract the rest.
4 - 3 = 1
7 - 3 = 4
12 - 3 = 9
19 - 3 = 16
28 - 3 = 25
In this case, subtracting 3 to all the numbers gave us perfect squares! So this means the nth term has to do with squaring the number and adding three afterward! This can be checked.
√1 = 1
√4 = 2
√9 = 3
√16 = 4
√25 = 5
As we found the values of these terms by subtracting three first and then finding its square root, the nth term will be the opposite; squaring and then adding three! Again, this can be checked!
1² + 3 = 4
2² + 3 = 7
3² + 3 = 12
4² + 3 = 19
5² + 3 = 28
Hope this helps !! :D
A is equal to 907 but not 907.3
So D is the answer
Square root of area = (13y + 10) cm = length of each side of the square piece.
perimeter is
p = 4(13y + 10)
= 52y + 40 Answer
when y= 10 p = 560 answer
Option C is the correct one.
