scoundrel [369]2 years ago
7 0

Step-by-step explanation:

  • (3x-2y) (4x+3y) (8x-5y)
  • (3x(4x+3y)-2y(4x+3y))(8x-5y)
  • (12x²+9xy-8xy-6y²)(8x-5y)
  • (12x²+xy-6y²)(8x-5y)
  • 12x²(8x-5y)+xy(8x-5y)-6y²(8x-5y)
  • 96x³-60x²y+8x²y-5xy²-48xy²+30y³
  • 96x³-52x²y-53xy²+30y³

If f(x)=x*−81 and g(x)=(x−9)−1(x+9), find g(x)×f(x).
Nostrana [21]
F(x) = x²-81

g(x) = (x-9) -1(x+9)

= (x-9) -x-9


g(x) • f(x)



= [x²-81 ] • [ (x-9) -x-9 ]

=[ x²-81 ] • [ (x-x -9-9) ]
= [ x²-81 ] •[0-18]
= [ x²-81] •[ -18]

= -18•x² +-81•-18
= -18x²+1458

Please can someone help my assignment​
Vadim26 [7]

Answer:

Find answers below

Step-by-step explanation:

First know that any value raise to power zero is 1 and also according to the inverse law;

a⁻ⁿ = 1/aⁿ

Given the following

a) (-123)⁰ = 1 ()Note that any value raise to zero is 1

b) 43⁻⁵ = 1/43⁵

1/43⁵ = 1/147,008,443

c) 1/15⁻⁶ = 1/(1/15⁶)

1/(1/15⁶) = 1*15⁶/1

1/(1/15⁶) = 15⁶

d) -(1353348)⁰

= -1 (anything raise to zero is 1)

e) 13⁻⁴ = 1/13⁴

= 1/28,561
