A famous Hindu mathematician, Aryabhata, showed (in around 500 C. E.) you could add up the first n triangular numbers with a relatively simple formula: n(n + 1)(n + 2) =T + T2 + T3 + ... + Tn 6 Use this fact to find the sum of the first 53 triangular numbers. The sum of the first 53 square numbers is

26,235

Step-by-step explanation:

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
