Which could be the first step in solving the equation represented by the model below? xx

II

Add 4 negative unit tiles to both sides.

Add 4 negative unit tiles to the left side, and add 6 negative unit tiles to the right side.

Add 4 positive unit tiles to both sides.

O Add 6 negative unit tiles to the left side, and add 4 negative unit tiles to the right side.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .

step-by-step explanation:

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
