Answer:

  • -11/5 or -1/4

Step-by-step explanation:

There are two possibilities in this question.

<h3>________________________________________________</h3>

<u>Possibility No. 1</u>

Given:

  • b/2a + b
  • b = -2
  • a = 5

<u>Step-1: Substitute the values given into the equation.</u>

  • b/2a + b
  • => -2/2(5) + (-2)

<u>Step-2: Solve.</u>

  • => -2/10 - 2
  • => -1/5 - 2
  • => -11/5

<u>Hence, the solution for possibility No. 1 is -11/5.</u>

<h3><u>________________________________________________</u></h3>

<u>Possibility No. 2</u>

Given:

  • b/2a + b
  • b = -2
  • a = 5

<u>Step-1: Substitute the values given into the equation.</u>

  • b/2a+b
  • => -2/2(5)+(-2)
  • => -2/10 - 2
  • => -2/8
  • => -1/4

<u>Hence, the solution for possibility No. 2 is -1/4.</u>

Ivan

Answer:

8\frac{3}{4} cups.

Step-by-step explanation:

From the line plot made by Diego which represents bottle sizes in cups, we can see that the most common size is the bottle having 1¾ cups (there are 5 of this sizes).

If he poured all 5 of this bottle sizes in 1 container, he would have the following:

1\frac{3}{4} * 5 = \frac{7}{4}*5 = \frac{35}{4}

= 8\frac{3}{4} cups.

spin [16.1K]

9514 1404 393

Answer:

  7x^3 +11x^2 -5x -8

Step-by-step explanation:

Combine like terms.

  (4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)

  = (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)

  = 7x^3 +11x^2 -5x -8

_____

Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...

  (4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)

  = (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)

  = 7x^3 +9x^2 -3x -8
