Given:
Sum of arithmetic sequence is 21.
Product of arithmetic sequence is 315.
I did a manual computation. Arithmetic sequence means that there is a constant difference between the two consecutive numbers.
x + (x+2) + (x + 2 + 2) = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
x = 15/3
x = 5 1st number
x + 2 = 5 + 2 = 7 2nd number
x + 2 + 2 = 5 + 2 + 2 = 9 3rd number.
5 + 7 + 9 = 21
5 x 7 x 9 = 315
I believe the correct answer is B
The answer is 20.6 because 17+3=20 and then you add the decimal so 20+0.6= 20.6
If it was 20 inches x 10 inches the perimeter would be 60 inches. which is the smallest possible perimeter with whole numbers
Answer:
8 to the power of 4
Step-by-step explanation:
since their are four 8, (8x8x8x8) , you have to put that into an exponent
still need proof?
8x8x8x8=4096
8 to the power of 4 = 4096
so to conclude, 8 to the power of 4 is the same thing as saying 8x8x8x8, it is jsut the exponent version
