Show how to use the identity below to calculate the sum of the cubes of your numbers without using a calculator.

a3 +b3 =(a+b)(a2 −ab + b2)

CHOOSE ONE set, A, B, or C to use for the following:

A) a=9 and b=12

B) a=10 and b=14

C) a=11 and b=13

Rewritten as the sum of cubes:



Calculate the sum of the cubes without using a calculator:

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
