52² − 48² = (2704 + 2304)(2704 − 2304) = 2,003,200
52² − 48² = (52 + 48)(52 − 48) = 100 * 4 = 400
a² - b² = (a +b)*(a-b)
52² − 48² = 2704 − 2304 = 400

Answer:
79 dollars
Step-by-step explanation:
a = 51 + b
Substitute the number of books, 28, he sold into the equation and solve for his earnings.
a = 51 + b
a = 51 + 28
a = 79
A linear equation in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. It's possible to simplify this to y = mx + b, where m = ( −A / B) and b is the value of y when x = 0. A quadratic equation, on the other hand, involves one of the variables raised to the second power. It has the general form y = ax2 + bx + c. Apart from the adding complexity of solving a quadratic equation compared to a linear one, the two equations produce different types of graphs.
The inference shows that the correct options that will fill the information will be:
- I need to study harder to understand the lesson.
- I realize that my knowledge will improve in this lesson..
- I need to study more to be able to explore more in the activity.
<h3>What is an inference?</h3>
An inference means the conclusion that can be deduced from the information given in a literary work.
In this case, it's important that one checks the information and correctly put in the options.
The learner communicates the explanation of their personal assessment as indicated in the Learner’s Assessment Card. • The learner, in their notebook, will write their personal insights about the lesson using the prompts below. I understand that ___________________. I realize that ________________________. I need to learn more about __________.
