Answer:

<h2>True.</h2>

Step-by-step explanation:

The given expression is

\frac{x^{3}-1}{x^{3}+x^{2}+x}

This expression is rational, which means the denominator must be different to zero, otherwise, the function will be undefined. So, let's find if there are values that make the denominator zero.

\frac{x^{3}-1}{x^{3}+x^{2}+x}=\frac{x^{3}-1}{x(x^{2}+x+1)}

So, if we evaluate the expression with x=0, we would have

\frac{x^{3}-1}{x(x^{2}+x+1)}=\frac{0^{3}-1}{0(0^{2}+0+1)}=\frac{-1}{0}

As you can observe, there must be one exclusion, because it makes the expression undefined.

Therefore, the answer is true.

Figure 22: Find the total yellow area.
Pachacha [2.7K]

Step-by-step explanation:

area of rectangle = l × h

= 9 × y

= 72

9 × y = 72

y = 72÷9

y = 8cm

area of circle = 50.27cm²

total area of the logo = 2(50.27) + 72

= 100.54 + 72

= 172.54cm²
