Answer:
1 - expressions that are equal in value even though they are written in different ways, 2 - a(b + c) = ab + ac, or a(b + c) = ab - ac, 3 - a number that divides evenly into another number; a number multiplied to get a product, 4 - a single term; multiple terms connected by an addition or subtraction sign, 5 - a mathematical statement that shows two expressions are equal using an equal sign, 6 - an expression that uses variables to state a rule, 7 - a relation in which for any given input value, there is only one output value.
Answer:
One solution (0, 3).
Step-by-step explanation:
As both expressions in x are equal to y:
3x + 3 = -2x + 3
3x + 2x = 3 - 3
5x = 0
x =0.
So y = 3(0) + 3 = 3.
Here is the expansion of <span>(x + y)n </span><span>for </span><span>n = 0, 1,…, 5</span><span> :</span>
<span>(x + y)0 = 1</span>
<span>(x + y)1 = x + y </span>
<span>(x + y)2 = x 2 +2xy + y 2 </span>
<span>(x + y)3 = x 3 +3x 2 y + 3xy 2 + y 3 </span>
<span>(x + y)4 = x 4 +4x 3 y + 6x 2 y 2 +4xy 3 + y 4 </span>
<span>(x + y)5 = x 5 +5x 4 y + 10x 3 y 2 +10x 2 y 3 +5xy 4 + y 5
</span>

Answer:
All values are identical.
Step-by-step explanation:
We are given the following in the question:
If the standard deviation of a set of data is zero.
Then, all the values in data are identical.
This can be shown as:
Let all the terms in data be x.
Formula:
where 
are data points, 
is the mean and n is the number of observations.
Sum of squares of differences =
Thus, the correct answer is
All values are identical.
