One can solve this by first using order of operations, and then combining like terms.
First is parenthesis
9x + 2x(9) - 2(9x)
Now we do the multiplication
9x + 18x - 18x
Now we combine like terms
9x
The sum of the digits, B. thirteen and one eighth, is the product of the numerals.
<h3>How do you compute the value of the product?</h3>
According to the data, we are in the negative four hundred and one-sixth times the negative three hundred and fifteen-hundredths range.
This is going to be the product:
= (-4 1/6) × (-3 15/)
= - 4 1/6 × 3 3/20
= - 25/6 × -63/20
x= 13 1/8
In conclusion, The answer that you should choose is an option (d), which is thirteen and one-eighth.

To do this, complete the square:
p(x) = 21 + 24x + 6x2 => <span>p(x) = 6x2 + 24x + 21
Rewrite the first 2 terms as
6(x^2 + 4x)
then you have </span><span>p(x) = 6(x2 + 4x ) + 21
Now complete the square of x^2 + 4x:
p(x) = 6(x^2 + 4x + 4 - 4) + 21
= 6(x+2)^2 - 24 + 21
p(x) = 6(x+2)^2 - 3 this is in vertex form now.
We can read off the coordinates of the vertex from this: (-2, -3)</span>
