Step-by-step explanation:
The factors of the trinomial based on the information given include:
C. x – 7
E. x + 2
<h3>What is a trinomial?</h3>
It should be noted that a trinomial is an algebraic expression that has three non-zero terms. Here, the examples of a trinomial expression: x + y + z is a trinomial in three variables x, y and z. Also, 2a² + 5a + 7 is a trinomial in one variables.
In this case, the algebra tile configuration has 0 tiles are in the Factor 1 spot and 0 tiles are in the Factor 2 spot. 24 tiles are in the Product spot: 1 is labeled + x squared, 7 are labeled negative x. Here, the trinomial is x² - 5x - 14.
The factors will be:
x² - 5x - 14.
x² + 2x - 7x - 14
x(x + 2) - 7(x + 2)
= (x + 2)(x - 7)
A polynomial with three terms is called a trinomial.
In conclusion, the correct options are C and E.

Answer:
b. 224
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem:
We want to find n, when
So






The nearest integer number to 223.9 is 224.
So the correct answer is:
b. 224
