= x( -7x^2) + x * 39x * 136

= -7x^3 + 39x^2 + 136x

Ugo [173]

Answer:

291.87 is a rational number.

Step-by-step explanation:

Rational numbers are those numbers that can be expressed in fractions that is can be written as $\frac{p}{q}$ where p and q are integers and $q\neq 0$ .

Consider the given number 291.87

Rewrite the decimal number as a fraction with 1 in the denominator, we get,

$291.87=\frac{291.87}{1}$

Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10² = 100

$\frac{291.87}{1}=\frac{29187}{100}$

Thus, the above fraction can be written as,

$\frac{29187}{100}=291\frac{87}{100}$

Thus, 291.87 is a rational number.
