Factored form refers to the form of a number or algebraic expression when it has been broken down into a product of its factors
Standard form is a way of writing down very large or very small numbers easily.
Answer:
80
Step-by-step explanation:
10+10= 20
20+20=40
40+40=80
Answer: The answers are (a)1/8th (b) 0.125 (c) 12.5%
Step-by-step explanation:
How I drew this conclusion is, you have 8 letters in RECORDER so its 8/64 the same spot for every letter which simplifies to 1/8th. Now for the decimal divide 8 into 64 to get 0.125 decimal form. Lastly, for the percent 8 * 100 = 0.125 then 0.125 * 100 gets you 12.5%. Hope this helps you understand good luck.
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: Option d: -3*x^4*y + 2*x^2*y^2 + 5*y^3
Step-by-step explanation:
In standard form, the first term of the polynomial must be the term with the highest degree and on each subsequent term the degree decreases. In the case of two variables, the degree is equal to the sum of the exponents.
Then the correct option is d.
Where the degree of the first term is (4 + 1) = 5
The degree of the second term is (2 + 2) = 4
The degree of the third therm is 3.
We can see that the degree decreases as the term number increases, then the polynomial written in standard form is:
-3*x^4*y + 2*x^2*y^2 + 5*y^3
