For a square with a side length x + 1 , what is the area if x=9

Svetach [21]

Answer:

100 units squared

Step-by-step explanation:

The area of a square is A=s^2, where s is the side length. So, in your problem, the area would be A=(x+1)^2. If x = 9, then the formula would be A = (9+1)^2 = 100.

Simplifying an Expression with the Numerator and the Denominator Raised to a Power

slamgirl [31]

Answer:

The answer to your question is the second option $\frac{1}{x^{48}y^{36}z^{6}}$

Step-by-step explanation:

Expression

$[\frac{(x^{2}y^{3})^{-2}}{(x^{6}y^{3}z)^{2}}]^{3}$

Process

1.- Divide the fraction in numerator and denominator

a) Numerator

[(x²y³)⁻²]³ = (x⁻⁴y⁻⁶)³ = x⁻¹²y⁻¹⁸

b) Denominator

[(x⁶y³z)²]²= (x¹²y⁶z²)³ = x³⁶y¹⁸z⁶

2.- Simplify like terms

a) x⁻¹²x⁻³⁶ = x⁻⁴⁸

b) y⁻¹⁸y⁻¹⁸= y⁻³⁶

c) z⁻⁶

3.- Write the fraction

$\frac{1}{x^{48}y^{36}z^{6}}$
