Answer: Yes, it is A!

Step-by-step explanation:

it is a because, you can have 30 baseball cards, and six packages, so imagine this has six bags full of a certain amount of candy, and there is 30 pieces of candy, and do you want to separate them into an even amount, so this would be 30÷6= ? The? Would be 5 as in to say The constant of proportionality would also be 5.

Answer:

Option A is the correct answer.

Explanation:

 There are 6 packages that store 30 baseball cards.

  Number of cards in 1 package = 30/6 = 5

  Let us consider a as number of packages and b as number of cards.

  We have equation for number of cards,

                      b = 5 a

          The constant of proportionality = 5

Option A is the correct answer.

General Formulas and Concepts:

<u>Algebra I</u>

  • Composite Functions
  • Combining Like Terms

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 4x² + 1

g(x) = x² - 5

(f + g)(x) is f(x) + g(x)

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

  1. Substitute:                    (f + g)(x) = 4x² + 1 + x² - 5
  2. Combine like terms:    (f + g)(x) = 5x² - 4

Answer:

  47 -6√10

Step-by-step explanation:

As you know, the area of a square is the square of the side length. It can be helpful here to make use of the form for the square of a binomial.

  (a -b)² = a² - 2ab + b²

  (√2 -3√5)² = (√2)² - 2(√2)(3√5) + (3√5)²

  = 2 - 6√10 + 3²(5)

  = 47 -6√10

__

<em>Check</em>

  √2-3√5 ≈ -5.29399 . . . . . . . . note that a negative value for side length makes no sense, so this isn't about geometry, it's about binomials and radicals

  (√2-3√5)² ≈ 28.02633

  47 -6√10 ≈ 28.02633
