which property is illustrated by the following statement? 2(-3/9)=(-3/9)2^? Associative Property of Addition, Commutative Proper

Ratling [72]

Consider the given statement:

$2(\frac{-3}{9}) = (\frac{-3}{9})2$

We have to identify the property used in this statement.

1. Associative Property of Addition: Let a,b and c be three real numbers. This property states that $a+(b+c) = (a+b)+c$ . This property is not used in the given statement.

2. Commutative property of multiplication: Let 'a' and 'b' be two real numbers. This property states that $a \times b = b \times a$ .

In the given statement, $2(\frac{-3}{9}) = (\frac{-3}{9})2$

This statement holds commutative property of multiplication as whether 2 is multiplied to $\frac{-3}{9}$ or $\frac{-3}{9}$ is multiplied to 2, the result is same.

So, Commutative property of multiplication is illustrated in this statement.

3. Inverse property of multiplication: A number 'a' is said to have an inverse ' $\frac{1}{a}$ ' if $a \times \frac{1}{a}=1$ . This property is not used in the given statement.

4. Commutative property of addition: Let 'a' and 'b' be two real numbers. This property states that $a+b = b+a$ . This property is not used in the given statement.

A 10 foot ladder is placed 4-feet from the edge of a building. How far up the building does the ladder reach? Round your answer

MariettaO [177]

Answer:

9.2 feet. b.)

Step-by-step explanation:

This uses the Pythagorean Theorem

Do you notice that the ladder forms a right triangle with the building.

10 feet = hypotenuse length

4 feet = bottom leg length

x feet = height of building

so 10^2 = 4^2 + x^2

100 = 16 + x^2

84 = x^2

x = root(84) = 9.16515 feet about 9.2 feet
