Rewrite 512x^3 as (8x)^3
(8x)^3 + 2197y^3
Rewrite 2197y^3 as (13y)^3
(8x)^3 + (13y)^3
Since both terms are perfect cubes, factor using the sum of cubes formula.
a^3 + b^3 = (a + b)(a^2 - ab + b^2) where a = 8x and b = 13y.
(8x + 13y)((8x)^2 - (8x)(13y) + (13y)^2)
Simplify
(8x + 13y)(64x^2 - 104xy + 169y^2)
Answer: The answer is = 2x^2 -11x-40
Step-by-step explanation: a= 2x, b=5, c= x, d =8
= 2xx + 2x (-8) + 5x +5(-8)
+ (-a)=-a
then simplify =2xx-2 -8x+5x.8
2xx=2x^2
2.8x=16x
5.8=40
=2x - 16x + 5x- 40
10n - 20p + 20

<span>8[(40-15) divided by 5]+3
Subtract 15 from 40
8(25/5)+3
Divide 25 by 5
8(5)+3
Multiply 8 by 5
40+3
Add
Final Answer: 43</span>
Okay i believe the first one is 4/7 and the second one is 2. also don’t listen to them. sometimes it can be hard and you start to stress. good luck and if this isn’t right i’m so sorry :) keep your head up!!!
