Answer:
The Percent change is -30% (decrease)
In this case we have a negative change (decrease) of -30 percent because the new value is smaller than the old value.
Step-by-step explanation:
Here, To find the percentage change, use this formula
<h3>
<u>Formula</u>:</h3>
Percent change = New - Old ÷ |Old| × 100%
Percent change = 210 - 300 ÷ |300| × 100%
Percent change = -90/300 × 100%
Percent change = -30% (decrease)
Thus, The Percent change is -30% (decrease)

An expression has numbers, variables, and mathematical operations. The equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².
<h3>What is an Expression?</h3>
In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
A perfect square trinomial is in the form (a+b)²=a²+b²+2ab. If we compare the perfect square trinomial x²+mx+m, we will get that the value of m should be such that it satisfies the equation 
. Since there is only one value that can satisfy this equation that is 2.
Therefore, the equation that must be true so that x²+mx+m is a perfect square trinomial is x²+mx+m=(x+2)².

The answer is 96
Yes it does match the graph
Answer:
9
Step-by-step explanation:
Working backwards, the blank box between the 7 and 4 at the end must be 9 in order for the three digits to equal 20. Then we see the pattern of 947 repeated. The whole number would be 94794794794794. That way, any three consecutive numbers would be 20. The number in the box marked a would be 9.
