Answer:

The answer is 4a+20

Step-by-step explanation:

This is because when you are using the distributive property, the number outside the parentheses has to multiply the two 2 numbers inside.

So 4*a=4a

and 5*4=20

Now all that is left is addition sign inside. All you have to do now is to combine the 2 terms which makes it 4a+20.

Marissa owns 135 shares of stock. Her dividend is $0.50 per share. How many shares can she buy of a different stock selling for

belka [17]

Answer:

- If the new stock is selling for $11 per share, Marissa can buy 6 shares.

- If the new stock is selling for 11 cents per share, Marissa can buy 613 shares.

Step-by-step explanation:

The question is not totally clear with the last statement.

- How many shares can she now buy of a different stock, selling for $11 per share?

- How many shares can she now buy of a different stock, selling for 11 cents per share?

Marissa has 135 shares of stock

Each share has a dividend of $0.50 per share,

The dividend from her 135 shares of stock would be 135 × $0.5 = $67.5

How many shares can she now buy of a different stock, selling for $11 per share?

= ($67.5/$11) = 6.14 ≈ 6 shares

If the new stock is selling for 11 cents per share, the number of shares she can buy = (67.5/0.11) = 613.6 ≈ 613 shares

Hope this Helps!!!

Use expressions for odd integers to confirm the conjecture that the product for two odd integers is an odd integer.

Mandarinka [93]

k, n - integers

2k+1 - an odd integer

2n+1 - another odd integer

The product of them:

(2k + 1)(2n + 1) =

= 4kn + 2k + 2n + 1 =

= 2(2kn + k + n) + 1

The product of integers (2kn) is integer

and the sum of them (2kn+k+n) also is integer

So (2k + 1)(2n + 1) = 2(2kn + k + n) + 1 is an odd integer
