Answer:
Following are the description of the given course code:
Step-by-step explanation:
The given course code is Pre-Algebra, which is just an introduction arithmetic course programs to train high school in the Algebra 1. This course aims to strengthen required problem solving skills, datatypes, equations, as well as graphing.
- In this course students start to see the "big picture" of maths but also understand that mathematical, algorithmic, and angular principles are intertwined to form a basis for higher mathematics education.
- The duration of this code is in year and it is divided into two levels. In this, code it includes PreK to 12 Education Courses
, with the general mathematics
.

Answer:
Not correct
Step-by-step explanation:
Given:
x² - 6x - 7 = 0
The following equation can be solved correctly by factoring Thus,
x² - x + 7x - 7 = 0
x(x - 1) +7(x - 1) = 0
(x - 1)(x + 7) = 0
(x - 1) = 0
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1
Or
(x + 7) = 0
x + 7 = 0
x + 7 - 7 = 0 - 7
x = -7
Therefore, the solution would be x = 1 or x = -7
Lateena solution is therefore NOT CORRECT because she used a wrong method.
Answer:
The height of the window is <u>38 inches</u>.
Step-by-step explanation:
Given:
A window is shaped like a parallelogram.
The base is 16 inches long.
The area is 608 square inches.
Now, to find the window's height.
Let the height be 
The area = 608 square inches.
The base (
) = 16 inches.
Now, to get the height of the window we put formula:

<u><em>Thus, the height is 38 inches.</em></u>
Hence, the height of the window is 38 inches.
