The distributive property of multiplication over addition is used when we multiply a number by a sum.

For example:

Lets suppose we want to multiply 7 by the sum of (15+3). So, according to this property, we can add the numbers and then multiply by 7.

It can be written like this :

$7(15+3)$

$7(18)$

= 126

1/5 times 26 estimated

disa [49]

Multiply 1/5 and 26/1 across the top and bottom, and you get 26/5

From there, you can estimate that its a little more than 5 because you know that 25/5 is 5 and 26/5 should be a tiny bit greater.

Hope this helped!

VLD [36.1K]

Answer:

$b)\: 12(5x^2+4x+2)$

Step-by-step explanation:

The given expression for water bottles is

$60x^2+48x+24$ .

The highest common factor of all the terms of this expression is $12$ .

We now factor to obtain;

$12(5x^2+4x+2)$

Hence the the factorization that represents the number of water bottles and the weight of each bottle is the one in option B.

The correct answer is B

We therefore factor to obtain,
