Answer:
13/28 (13 over 28)
Step-by-step explanation:
26/28 - 13/28 = 13/28 and since 13 is a prime number it can't be simplified
Answer:
Many options - 4/6 or 2/3 or 0.66
Step-by-step explanation:
When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !
Answer:

Step-by-step explanation:
Here, we have to find the sum of 2 fractions:
1st fraction: 
2nd fraction: 
Considering the denominator of 1st fraction:

Using factorization method:
can be written as
.

Taking <em>5 common</em> from
and <em>y common</em> from
:

Now taking
common:

can be written as 
Now, calculating the sum:

Taking <em>LCM</em> and solving:

Hence, answer is
.
Answer: x^3 - a^3 = (x - a) (x^2 + ax + a^2) is an identity
Step-by-step explanation:
Verify the identity using trig rules.
Answer:

Step-by-step explanation:
Explicit formulas are used to represent all the terms of the geometric sequence with a single formula.

a is the first term.
r is the common ratio.
r = second term ÷ first term.
3 , - 6 , 12, - 24, 48 ,........
a = 3
r = -6 ÷ 3 = -2
