Answer:

x^4 + 4x^3 + 6x^2 + 7x + 2

Step-by-step explanation:

We are asked to multiply the given polynomials.

(x^ 2 + 3x + 1) \times (x^2 + x + 2)

Multiply each term of the first polynomial to each term of the second polynomial.

x^ 2  \times (x^2 + x + 2) = x^4 + x^3 + 2x^2

3x  \times (x^2 + x + 2) = 3x^3 + 3x^2 + 6x

1 \times (x^2 + x + 2) =  x^2 + x + 2

Add the results

(x^4 + x^3 + 2x^2) + (3x^3 + 3x^2 + 6x) + ( x^2 + x + 2)

Combine the like terms

x^4 + 4x^3 + 6x^2 + 7x + 2

The answer is written in descending powers of x.

Monica has $20. She needs to buy a gallon of milk that costs $2.50. She also wants to buy yogurt, which costs $1.20 a cup. What
Kitty [74]

We are given : Cost of a gallon of milk = $2.50.

Cost of a cup of yogurt = $1.20.

Total money Monica has = $20.

Number of cups of yogurt Monica can buy = x.

And inequality made is also correct

1.20x + 2.5 ≤ 20.

Now, we need to solve it for x.

Subtracting 2.5 from both sides, we get

1.20x + 2.5 -2.5 ≤ 20 - 2.5.

1.20x ≤ 17.5

Dividing both sides by 1.20, we get

1.20x/1.20 ≤ 17.5/1.20.

x ≤ 14.5833...

Because it's less than 15, so final answer is : 14 is  greatest number of cups of yogurt Monica can buy.
