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: 
<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) 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 
Since 28 = 7 times 4 and 35 = 7 times 5
Thus,

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

Answer:
-16.4, (commutative property)
Step-by-step explanation:
(add, because they are both negatives) -5.2+(-8.4)= -13.6
Then add the (-2.8): -13.6 + (-2.8) = -16.4
Thats your first equation!!!
do the same thing for the other one, and by the way it the same answer.
Its commutative prop because its just switching positions and its adding negatives.
Answer:
1. Fala can paint more than one whole step
2. She can paint 3 steps
Step-by-step explanation:
1. In the second question we found that she has enough for 3 steps and 3 is more than 1 so she can paint more than one step
2. 6/4=12/8 so she has 12/8 quarts and needs 4/8 for each step
Divide 12 by 4 = 3 So she has enough paint for 3 steps
