Answer:

The answer to your question is:

Step-by-step explanation:

(4 + 5) + 2 = 4 + (5 + 2)                     Associative property of addition

2(2x + 4) = 4x + 8                             Distributive property

( 7 x ) 3 = 7 (x 3)                                Associative property of multiplication

( 8 x 2) = (x 8 2)                                Commutative property of multiplication

( 7 + 3) + 1 = 1 + (7 + 3)                       Commutative property of addition

Answer:

(4+5)+2=4+(5+2)                    Associative property of addition

2(2x+4)=4x+8                         Distributive property

(7x) × 3 = 7(x × 3)                    Associative property of multiplication

(8 × x × 2) = (x × 8 × 2)           Commutative property of multiplication

(7+3)+1 = 1+(7+3)                     Commutative property of addition

Step-by-step explanation:

Associative property of addition : It is a property when we are adding numbers then we can group the numbers in any combination.

For example : a+(b+c) = (a+b)+c

Associative property of multiplication : It is a property when we are multiplying numbers then we can group the numbers in any combination.

For example : a×(b×c) = (a×b)×c

Commutative property of addition : It is a property in which we can add numbers in any order.

For example : a+b = b+a

Commutative property of multiplication : It is a property in which we can multiply numbers in any order.

For example : a×b = b×a

Distributive property : It is a combination of addition and multiplication.

For example : a×(b+c) = (a×b) + (a×c)

If the total surface area of a cube is 302.46ft2 what best describes the length of the side of the cube?​
12345 [234]

Answer:

7.1ft

Step-by-step explanation:

The formula for calculating the total surface area of a cube is 2(L²+L²+L²)

=2(3L²)

= 6L²

Where L is the length of the cube

If the total surface area of a cube is 302.46ft², then

302.46 = 6L²

L² = 302.46/6

L² = 50.41

L =√50.41

L = 7.1ft

The length of the side of the cube is 7.1ft

RUDIKE [14]

Answer:

Step-by-step explanation:

It's D.

A theorem is true by some sort of mathematical logic.

It is not a definition. Not C

It is not in the end true because of inductive reasoning (a theorem may lend itself to inductive reasoning, but it must be proved.) Not A

It certainly not assumed to be true without proof. Not B

Which is equivalent to the equation given below ;
Anestetic [448]

Answer:

y = log6 (15)

Step-by-step explanation:

6^y = 15

Take the log base 6 of each side

log6(6^y) = log6(15)

We know log (a^b) = blog a

y log6 (6) = log6 (15)

We know that log6(6) =1

y = log6 (15)
