Answer:

-3 over 4=x

Step-by-step explanation:

x:1÷4(2x+4)=4

x over 1÷4(2x+4)=4

x over 1×1 over 4(2x+4)=4

x over 4(2x+4)=4

x=4×4(2x+4)

x=32x+64

x-64=32x

-64 over 32= 2x

-3 over 2=2x

-3 over 2÷2=x

-3 over 2 × 1 over 2=x

-3 over 4 =x

i am not sure about my answer tho

Max points easy math problem
11Alexandr11 [23.1K]

Solution:

Given:

  • x = -4
  • y = 4

<u>Substitute the values into the equation:</u>

  • x⁶ - x/4y
  • => [(-4)⁶] - (-4)/4(4)

<u>Simplify the numerator and the denominator:</u>

  • => [(-4) x (-4) x (-4) x (-4) x (-4) x (-4)] + 4/16
  • => [(-64) x (-64)] + 4/16
  • => [4096] + 4/16
  • => 4100/16

<u>Simplify the fraction:</u>

  • => 4100/16
  • => 1025 x 4/4 x 4
  • => 1025/4

Correct option is B.
