Answer:

${15x}^{2} + 90x + 135 \\$

Step-by-step explanation:

$15 {(x + 3)}^{2} \\ 15(x + 3)(x + 3) \\ 15 |(x(x + 3) + 3(x + 3)| \\ 15( {x}^{2} + 3x + 3x + 9) \\ 15( {x}^{2} + 6x + 9) \\ {15x}^{2} + 90x + 135 \\$

Answer:

"2" is the exponent

Step-by-step explanation:

There is no exponent in your expression.

When the expression is typeset, the superscript text is considered to be an exponent:

$15(x+3){\boxed{^2}}$

When the expression is written in plain text, the exponent is indicated by a caret (^):

$\textsf{15(x+3)\^\ \!\!\boxed{\textsf{2}}}$

There would be 6 waters and 5 snack mixes. Each water is 1.25, so 1.25x6 would be 7.50. And each snack is 2.50, so 2.50x5 would be 12.50. Adding those two or es together would be exactly $20 and adding all the items is 11. Hope this helps:)

Suppose an oligopoly consists of two firms. Firm A lowers price and Firm B responds by lowering its price by the same amount. If

VMariaS [17]

Answer:

The profits for firma A and B will decrease.

Step-by-step explanation:

Oligopoly by definition "is a market structure with a small number of firms, none of which can keep the others from having significant influence. The concentration ratio measures the market share of the largest firms".

If the costs remain the same for both companies and both firms decrease the prices then we will have a decrease of profits, we can see this on the figure attached.

We have an equilibrium price (let's assume X) and when we decrease a price and we have the same level of output the area below the curve would be lower and then we will have less profits for both companies.
