42x can be factored into 7(6x), and 49 is square, meaning it can be factored into 7 squared. I believe the factored expression would be 7(6x + 7) because 7 is the greatest common factor between both numbers.
Try using negative numbers
Answer: 0.00133m/s
Step-by-step explanation:
Given
distance crawled by the snail = 6cm = 0.06m
Time taken = 0.75minutes = 0.75*60
Time taken = 45secs
Required
constant rate of change of the snail's crawl (speed)
Speed of the snail = distance/time;
Speed of the snail = 0.06/45
Speed of the snail = 0.00133m/s
Hence the constant rate of change of the snail's crawl in m/s is 0.00133m/s
Answer is 6/11
Explanation :-
Now open left side brackets and multiply 2 with each on left,
Now, bring the common values together for easier calculation.
As we cant divide 6/11 , we write it as it is.
Therefore, <em>value of x is <u>6/11</u></em>
Im not sure what x is supposed to be in the given example. If its x = 99
then the expression would be 2.102 = 2(103 - 1).
