ANSWER

{a}^{2}  + a - 6

EXPLANATION

The given expression is

(a + 3)(a - 2)

We expand using the distributive property to obtain:

a(a - 2)  + 3(a - 2)

We multiply out the parenthesis to get:

{a}^{2}  - 2a + 3a - 6

Let us now simplify by combining the middle terms to obtain;

{a}^{2}  + a - 6

Which correlation is most likely a causation?
melisa1 [442]
It is usually noted that correlation does not imply causation, but there are some correlations which are causation as well.

A correlation is when there is a relationship between two variables while causation is when the outcome of one variable affects the outcome of the other variable.

From the first option, though there may be a positive relationship between sales of jeans and sales of slacks, but the purchase of jeans does not mean that you have to purchase a slack, thus, there is no causation.

For the second option, though there may be positive relationship between <span>the number of aisles and the number of products in a supermarket, but a supermarket can have many aisles with few products, i.e. many aisles does not automatically imply many products, thus, there is no causation.

For the third option, though there may be a positive relationship between </span><span>the number of swimmers and the number of sunbathers at a beach, but all swimmers in a beach are not sunbathers and all sunbathers are not swimmers. Thus, a swimmer does not imply a sunbather and a sunbather does not imply a swimmer. Thus, there is no causation.

For the last option, it is generally known that the more you practice an activity, the better you get in that activity. Thus, there exist a relationship between </span><span>the number of hours spent practicing archery and the number of bull's-eyes an archer can hit and there also exist causation because the number of bull's-eye an archer can hit is directly dependent on the number of hours the archer spent practicing.

Therefore, the </span><span>correlation that is most likely a causation is </span><span>the positive correlation between the number of hours spent practicing archery and the number of bull's-eyes the archer can hit.</span>

Dont know how to calculate it
TEA [102]

Answer:

AB = 105

Step-by-step explanation:

Since ∠ A and ∠ B  are equal then Δ ABC is isosceles with 2 congruent legs.

AC = BC , substitute values

6x - 7 = 5x + 7 ( subtract 5x from both sides )

x - 7 = 7 ( add 7 to both sides )

x = 14

Then

AB = 7x + 7 = 7(14) + 7 = 98 + 7 = 105

The diameter of a circle is 16 kilometers.What is the circle's circumference?​
qaws [65]

The equation to find the circumference of a circle is ...

c = π × d

All we need to do to find circumference is to <em><u>multiply</u></em> the diameter (16km) by pi (π)

c = π × 16

c = 50.27
