2 × m + 3 × m² - 4 × m

Put parenthesis around parts of the equation, to make it easier to look at.

(2 × m) + (3 × m²) + (-4 × m)

Simplify.

2m + 3m² + (-4m)

Add like terms.

3m² + -2m

Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home

jek_recluse [69]

Answer:

120 home runs.

Step-by-step explanation:

Let x be the number of home runs after playing 1272 games.

We have been given that Derek Jeter, the short stop for the New York Yankees, a major league baseball team, played in 159 games in 2012 and hit 15 home runs.

Let us find the probability of hitting home runs in next game.

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{ Total number of possible outcomes}}$

$\text{Probability of hitting home run in next game}=\frac{15}{159}$

To find the total number of home runs Derek will hit in his career, we will use relative probability, which is the ratio of the occurrence of a singular event and the total number of outcomes.

So we can set a proportion as:

$\frac{x}{1272}=\frac{15}{159}$

Let us multiply both sides of our equation by 1272.

$\frac{x}{1272}*1272=\frac{15}{159}*1272$

$x=15*8$

$x=120$

Therefore, Derek Jeter will hit approximately 120 home runs in his career.

Write four different expressions for the perimeter of a pentagon whose sides are all s-2 units long

igor_vitrenko [27]

Answer: The answers are given below.

Step-by-step explanation: Given that all the sides of a pentagon are (s-2) units long. This clearly tells us that the pentagon is a regular one with each side equal to (s-2) units.

We are to write the perimeter of the pentagon in four different expressions.

Let 'P' represents the perimeter of the pentagon.

Since it is a regular pentagon, we can write the perimeter in following four expressions.

P = (s-2) + (s-2) + (s-2) + (s-2) + (s-2),

= 5 × (s-2),

= 5s - 10,

= 5s - 5×2.

Thus, these are the four expressions for the perimeter of the pentagon.
