Name the property the equation illustrates.<br><br> 7 + (4 + 4) = (7 + 4) + 4

galben [10]

Answer: Associative Property of Addition

Step-by-step explanation: The statement 7 + (4 + 4) = (7 + 4) + 4 represents the associative property of addition. Notice that the addends or the numbers we are adding are the same on both sides of the equals sign.

But on the left side, 4 and 4 are grouped together and on the right side, 7 and 4 are grouped together.

The <em>associative property of addition</em> says that when we are adding more than two numbers, the grouping of the addends does not affect the sum.

Here, the order operations tells us to begin inside the parentheses. So we have 4 + 4 which is 8 and 7 + 8 is 15.

On the right side, notice that 7 + 4 is 11 and 11 + 4 is also 15.

In general terms, we can write the associative property of addition as

(a + b) + c = a + (b + c) where <em>a</em>, <em>b</em>, and <em>c</em> are variables that can represent any number.

Which expression is equivalent to Negative 28 x y 35 y? 7 y (Negative 4 x y 5 y) 7 x (negative 4 x 5 y) 7 x (negative 4 y 5 y) 7

GREYUIT [131]

You can use the distributive property of multiplication over addition to find the equivalent expression to the given expression.

The expression which is equivalent to the given expression is given by

Option D: $7y(-4x + 5)$

<h3>What are equivalent expressions?</h3>

Those expressions who might look different but their simplified forms are same expressions are called equivalent expressions.

<h3>What is distributive property of multiplication over addition?</h3>

Suppose a, b and c are three numbers. Then we have:

$a(b + c) = a \times b + a \times c$

(a(b+c) means a multiplied to (b+c). The sign of multiplication is usually hidden when using symbols and both quantities which are in multiplication are written together without space)

<h3>Using the above property and the fact that 28 and 35 are multiples of 7 to get the equivalent expression</h3>

The given expression is $-28xy + 35y$
