Answer:
i think its b
Step-by-step explanation:
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.

Answer:
D.17
Step-by-step explanation:
We are given that inequality
x<15
We have to find the number which is not a solution of the given inequality.
x<15
It means the values of x which is less than 15.
A.-6
-6<15
Therefore, it is the solution of given inequality.
B.-2
-2<15
Therefore, it is the solution of given inequality.
C.11
11<15
Therefore, it is the solution of given inequality.
D.17
17>15
Therefore, it is not a solution of given inequality.
Option D is true.
