Squaring 39 means multiplying it by itself which amounts to C. 1,521
Squaring a number means multiplying it by itself. So, 39 squared is 39 multiplied by 39. This is equal to 1,521.
Here is the calculation:
39 × 39 = 1,521
Quite often, people confuse squaring with finding the square root of a number.
Taking the square root of a number means finding a number that, when multiplied by itself, equals the original number. For example, the square root of 25 is 5 because 5 × 5 = 25.

Which of the following could be the ages of Cory and Livy?
Livy could be 13 years old, and Cori could be 35 years old.
Livy could be 15 years old, and Cori could be 28 years old.
Livy could be 33 years old, and Cori Could be 10 years old.
Livy could be 20 years old, and Cori could be 85 years old.
Answer:
Livy could be 13 years old, and Cori could be 35 years old.
Step-by-step explanation:
Given : The system of inequalities describes the relationship between Cori’s age, C, and Livy’s age L.
C + L > 43
C - 4L < 3
We have to determine the ages of Cory and Livy.
We will plot both the inequality in a graph.
Thus, below attachment shows the graph of the two given inequality
Let x axis represent the Cori’s age, C, and y - axis Livy’s age L.
Now we plot the given ages in the graph and those points lies in intersection will given the ages of Cori and Livy.
Thus, Only (35 , 13) lies in the intersection,
We reject other points as the lies on dotted edges of graphs.
Thus, Livy could be 13 years old, and Cori could be 35 years old.
Answer:The system of inequalities below describes the relationship between Cori’s age, C, and Livy’s age, L.
C + L > 43
C - 4L < 3

Step-by-step explanation:
Paige's claim can be verified through three methods: substitution, elimination, and graphing. Each method involves using the potential solution (-2,-5) to determine if it is a valid solution to the given systems of linear equations.
The verification of Paige's claim that the solution to the systems of linear equations y=2x-1 and -12x+3y=9 is (-2,-5), can be achieved by using three distinct methods. These methods include: 1. Substitution; 2. Elimination; and 3. Graphing.
Substitution: You substitute the x and y values of the proposed solution into both equations to verify whether both are true. In this case, substituting x=-2 and y=-5 into both equations should confirm whether Paige's claim is correct.
Elimination: You can add or subtract the two equations in order to eliminate one of the variables and solve for the other. You then confirm if the solution matches Paige's claim.
Fianlly, Graphing: You graph both equations on the same axes and determine their point of intersection. If the point of intersection is (-2,-5), then Paige's claim is verified.

The number of ants after 60 days is 240.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The population of ants doubles every 20 days.
Current number of ants = 30
Now,
The number of ants after 20 days.
= 30 x 2
= 60
The number of ants after 40 days.
= 60 x 2
= 120
The number of ants after 60 days.
= 120 x 2
= 240
Thus,
The number of ants is 240.
