It is 135cm squared please give me brainliest
Answer:
Step-by-step explanation:
The picture does not show the example which will help in determining whether it is simple or compound interest calculation.
Based on what is shown, the answer is:
the numerator is: {(n + 11) + (n + 10) + (n + 9 ) + (n + 8) = 4n + 38;
and the denominator is: {(n) + (n + 1) + ... + (n + 11) = 12n + 66.
Therefore, the fraction is numerator/denominator:
= (4n + 38) / (12n + 66)
In this case n=1, the fraction = 42/78 = 0.53846
= 53.85%
Since both terms are perfect squares, you have to factor using the difference of squares formula where a=x and b=3
The formula for a^2-b^2 is...
(a+b)(a-b)
In this case the formula is 4(x+3)(x-3)
