Write the following phrase as a variable expression. Use X to represent “a number.” The sum of eleven, a number, and the product
melamori03 [73]

Answer:

11 + x + 19*x

Step-by-step explanation:

The sum of eleven, a number, and the product of nineteen and the number.

we have to read carefully and understand how to interpret

when he says the sum of separates into 3 parts because there is a "comma" and an "and"

Now let's separate the 3 parts of the sum

1 part

says eleven so we just put 11

eleven = 11

2 part

in the text it says that we replace "a number" with x

a number = x

3 part

In this case we simply make the product between the given values

the product of nineteen and the number

19 * x

Now we can accommodate everything and we finish

11 + x + 19*x

What is the value of k if 2x^3-3x^2+kx-4 is divided by x-3 and gives a remainder of -7?
Alik [6]

By the polynomial remainder theorem, the remainder upon dividing a polynomial p(x) by x-c is the same as the value of p(c).

Here p(x)=2x^3-3x^2+kx-4 and c=3. We have

p(3)=23+3k=-7\implies k=-10
