the sum of polynomials is 3x^{2} + 6x + 4

Step-by-step explanation:

Question:

(6x+7+x^{2}) + (2x^{2} - 3)

<em>Step 1: Open the bracket according to BODMAS rule</em>

6x+7+x^{2} + 2x^{2} - 3

<em>Step 2: Arrange</em>

x^{2}[/tex] + 2x^{2} + 6x + 7 - 3

<em>Step 3: Simplify</em>

3x^{2} + 6x + 4

Therefore, the sum of polynomials is 3x^{2} + 6x + 4

General Formulas and Concepts:

<u>Algebra I</u>

  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = x² - 11x + 18

g(x) = x - 9

<u>Step 2: Find f(x) + g(x)</u>

  1. Substitute:                              f(x) + g(x) = x² - 11x + 18 + x - 9
  2. Combine like terms (x):          f(x) + g(x) = x² - 10x + 9

What is this trinomial in factored form? 3a^2-2a-1
Dafna1 [17]
<span>Simplifying 3a2 + -2a + -1 = 0 Reorder the terms: -1 + -2a + 3a2 = 0 Solving -1 + -2a + 3a2 = 0 Solving for variable 'a'. Factor a trinomial. (-1 + -3a)(1 + -1a) = 0 Subproblem 1Set the factor '(-1 + -3a)' equal to zero and attempt to solve: Simplifying -1 + -3a = 0 Solving -1 + -3a = 0 Move all terms containing a to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + -3a = 0 + 1 Combine like terms: -1 + 1 = 0 0 + -3a = 0 + 1 -3a = 0 + 1 Combine like terms: 0 + 1 = 1 -3a = 1 Divide each side by '-3'. a = -0.3333333333 Simplifying a = -0.3333333333 Subproblem 2Set the factor '(1 + -1a)' equal to zero and attempt to solve: Simplifying 1 + -1a = 0 Solving 1 + -1a = 0 Move all terms containing a to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1a = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1a = 0 + -1 -1a = 0 + -1 Combine like terms: 0 + -1 = -1 -1a = -1 Divide each side by '-1'. a = 1 Simplifying a = 1Solutiona = {-0.3333333333, 1}</span>

In the rectangle ABDF above, C and E are midpoints of sides line ED and line DF, respectively, what fraction of the areas of the
aivan3 [116]

Answer:

Is shaded 5/8 of the area of the rectangle

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The area of triangle ABC represent 1/4 of the total area

The area of triangle CDE represent 1/8 of the total area

The shaded region is composed by one triangle equal to triangle ABC and three triangles equal to triangle CDE

so

The area of the shaded region is equal to

(1/4)(1)+(1/8)(3)=(1/4)+(3/8)=(2/8)+(3/8)=5/8

therefore

Is shaded 5/8 of the area of the rectangle
