densk [106]3 years ago
4 0

Answer:

Elena is correct

Step-by-step explanation:

5 - (-6) * 4 + (-3)

5 - (-24) + (-3)

5 + 24 - 3

29 - 3 = 26

Start by multiplying (-6) * 4

Then rewrite your equation into 5 - (-24) + (-3)

A negative minus a negative equals a positive so you rewrite your equation to 5 + 24 - 3

Subtract 29 - 3 and you get 26 so therefor Elena is correct

Which term best describes a mathematical statement of the form shown<br> below?<br> If A then B.
Mkey [24]
<h2>Conditional statement.</h2>

A mathematical statement of the form 'If A Then B' is a conditional statement.

<h3>Explanation:</h3>

A conditional statement in geometry is an if-then statement consisting of a hypothesis and a dependent conclusion.  The structure of a conditional statement is:

<em>If (......hypothesis......), then (......conclusion......)</em>

If  hypothesis = A and conclusion = B, the mathematical expression for a conditional statement is:  <u>A → B</u> and it is read as <u>If A then B.</u>

A conditional statement is always true unless the hypothesis is true and the conclusion is false.

A conditional statement can be written in form of its converse, inverse and contrapositive.

<u>Example of a conditional statement is</u>

A = I am 18 years old

B = I am an adult

A conditional statement is of the form (<u>A → B</u>) "If A then B"; therefore

If I am 18 years old, then I am an adult.

Find the area of a regular polygon
Law Incorporation [45]

Answer: Area of the polygon is 43.31 cm^2 t

Step-by-step explanation:

The polygon show in the diagram is a hexagon. It has six sides, since it is a regular hexagon, all the six sides are equal.

From the information given, the apotherm = 5√3

The apotherm is the perpendicular distance from the center of one side of the polygon to the center of the polygon. To determine the area of the polygon,

Area of polygon

=area = a^2n ×tan 180/n

Area = (5√3)^2 tan(180/6)

Area = 5^2×(√3)^2 × tan30

Area = 25×3×0.5774

Area = 43.305

Approximately 43.31 cm^2 to the nearest tenth
