Please help me with these:

1. X + 5 / 4X + 20


2. (-5X)^ -1 (10X^2)

3. (-3X^-2)^0 (2X)^0 / 8

THANK YOU <3

1. (X + 5)/(4X + 20)=(x+5)/4(x+5)
=1/4

2. (-5X)^ -1 (10X^2)=10x²/-5x
=-2x

3. (-3X^-2)^0 (2X)^0 / 8=1(1)/8
=1/8

1. x + 5 / 4x + 20 = x + 5 / 4(x + 5) = 1/4

2. (-5x)^-1 (10x^2) = 1/(-5x) (10x^2) = (10x^2)/(-5x) = -2x

3. (-3x^-2)^0 (2x)^0 / 8 since any number to the zero power = 1 this simplifies to 1/8

Let me guess, first year Algebra?

1). (x + 5)/[4(x + 5)] = 1/4

2). (-5x)^(-1) *10x² = 10x²/(-5x) = -2x

3). if x is not zero then raise to the zero-power the result is 1. Numerator is 1. Answer is 1/8
