Basically, since both fractions have a like denominator, you just have to add across, but if the denominators were different, you'd have to to do more work. and it's the same without the denominators because all you're really doing is just crossing them out and adding across.
Answer:7n-1
Step-by-step explanation:
Nth term=6+7(n-1)
Nth=6-7+7n
Nth term=-1+7n
Nth term=7n-1
Answer:
0.5027 square meters
Step-by-step explanation:
cm2
The rule for this one is called the difference of squares
A^2 - b ^2 = (a+b)(a-b)
Using this rule
N^2 - 62 = (n+ sqrt(62)) (n - sqrt(62))
The solution for this one is to make the statement = 0
0 = (n+ sqrt(62)) (n - sqrt(62))
N can either be +- sqrt(62)
