Answer:
Step-by-step explanation:
(a³ - b³) = (a - b) (a² + ab + b²)
27x³ - 64 = 3³x³ - 4³
= (3x)³ - 4³ {a = 3x & b= 4)
Substitute in the above formula.
= (3x -4)([3x]² + 3x*4 + 4²)
= (3x - 4)(9x² + 12x + 16)
The expression 27x^3-64 factors to (3x-4) (9x^2+12x+16).
Answer:
$ 1650
Step-by-step explanation:
Denise's child tax credit for 2017 = ( 2 × $ 1000) - ( ( $ 81500 -$ 75 000) / $ 1000 × $ 50 ) = $ 2000 - $ 350 = $ 1650 where 6.5 factor is rounded to nearest whole number
x = -1
Simply get the variable on one side of the equation alone and simplify:
2x = 5 - 21/3
2x = 15/3 - 21/3
2x = -6/3
2x = -2
x = -1
35 is the answer cuz u do y2- y1 then x2- x1
