Super confused definitely need help on this

Marat540 [252]

Answer:

$(x-5)(x+8)=x^2+3x-40$

Step-by-step explanation:

So we have the expression:

$(x-5)(x+8)$

To multiply, distribute the left to the terms on the right:

$=(x-5)(x)+(x-5)(8)$

Distribute:

$=(x^2-5x)+(8x-40)$

Combine like terms:

$=(x^2)+(-5x+8x)+(-40)$

Simplify:

$=x^2+3x-40$

Therefore:

$(x-5)(x+8)=x^2+3x-40$

How are the values of -4^3 and 4^-3 alike and how do they differ?

BartSMP [9]

Answer:

(-4)³ = -64

(4)⁻³ = 1/64

Step-by-step explanation:

$( - 4) {}^{3} = ( - 4) \times ( - 4) \times ( - 4) = - 64 \\$

${4}^{ - 3} = (\frac{1}{4} ) {}^{3} \\$

$({ \frac{1}{4} )}^{3} = \frac{1}{4} \times \frac{1}{4} \times \frac{1}{4} = \frac{1}{64} \\$
