Answer:

D. Factor the simplified trinomial.

Step-by-step explanation:

We are given a trinomial ax^2 + bx + c..

We are given the first step, that is we have to find the common factor in each term.

After taking out the common factor out, then second step would be we need to factor the simplified trinomial.

So the answer is D. Factor the simplified trinomial.

For instance,

Consider the trinomial 2x^2 + 6x + 4

Step 1: Look at the common factor in each term.

Which is 2. Now factor 2, we get

2(x^2 + 3x + 2)

Now we got the simplified trinomial x^2 + 3x + 2

Step 2: Now we have to factor the simplified trinomial.

x^2 + 3x + 2 = (x + 1)(x +2)

So the answer is D) Factor the simplified trinomial.

<u>Answer</u>

A)  Factor out the common factor.

<u>Explanation</u>

Factorization is a process of looking for numbers that can be multiplied to get another number. It is expressing number as a product of other numbers.

The first step involves looking for numbers factors and the second one is factoring the common factors.

assume the age of night school students is normally distributed. A simple random sample of 24 night school students had an avera
aleksley [76]
Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)

The working equations is

\frac{(n-1) s^{2} }{ x^{2}_{right} }  \ \textless \   S^{2} \ \textless \   \frac{(n-1) s^{2} }{ x^{2}_{left} }

To find x^{2}_{right}, : (1 - 0.90)/2 = 0.05

To find x^{2}_{left}, : 1 - 0.05 = 0.95

Degrees of freedom = n-1 = 24 - 1 = 23

This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,

 x^{2}_{left} = 13.093 

 x^{2}_{right} = 35.17 


Substitute all values,

\frac{(24-1) 5.6^{2} }{ 35.17} \ \textless \ S^{2} \ \textless \ \frac{(24-1)  5.6^{2} }{ 13.093} }

Thus the answer is,

20.51\  \textless \ S^{2} \ \textless \ 55.09

450 yards in 15 minutes?
madam [21]

Answer:

30 yards per minute.

Step-by-step explanation:

Unit rate is basically when the denominator is 1. In this case, 450 is divisible by 15, so if you divide that, you get 30.

Laney builds a tower with wooden cubes. The bottom cube's edges are 8 centimeters long. The middle cube's edges are 2 centimeter
Mazyrski [523]

Answer: The total volume of the the cubes in the tower is 792 cubic centimetres (792 cm³)

Step-by-step explanation: We shall call the volume of the cube at the bottom VB, the volume of the cube at the middle VM, and the volume of the cube at the top VT. The tower is made up of cubes at different levels and at the bottom the cube measures 8 centimetres. The cube at the middle measures 2 cm less than the bottom cube, hence middle cube equals 8 minus 2 which equals 6 cm. The top cube measures 2 cm less than the middle cube, hence the top cube equals 6 minus 2 which equals 4 cm. The volume of each cube is given as;

Volume = L³

The length of a cube measures the same on all sides, that is, length, width and height. The length on all sides therefore of the bottom cube is 8 cm. The volume equals;

VB = 8³

VB = 512 cm³

The length on all sides of the middle cube is 6 cm (measures 2 cm shorter than the bottom cube). The volume of the middle cube equals;

VM = L³

VM = 6³

VM = 216 cm³

The length on all sides of the top cube is 4 cm (measures 2 cm shorter than the middle cube). The volume of the top cube equals;

VT = L³

VT = 4³

VT = 64

From the calculations shown, the total volume of the cubes in the tower is given as;

Total volume = VB + VM + VT

Total volume = 512 + 216 + 64

Total volume = 792 cm³

Total volume is 792 cubic centimetres.
