Answer:
Step-by-step explanation:
for reflection around x-axis.
(x,y)→(x,-y)
so P' is (-7,4)
A polynomial is a collection of terms that are separated by a plus or a minus sign. There a few types of polynomials.
Monomials have one term.
Binomials have two terms.
Trinomials have three terms.
All of these are classified as a polynomial.
Once you go over 3 terms, it's simply called a polynomial.
which one, and um this catagory is english
Answer: x is 90
Step-by-step explanation:
because x-20 is equal to 70
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.
