Solving two equations in two variables, one is of first degree and the other is of second degree

The video tutorial explains how to determine the dimensions of a triangular piece of cheese using its perimeter and the Pythagorean theorem. The problem is set up by forming two equations: one linear and one quadratic. By solving these equations, the dimensions of the triangle are found to be 18 and 24 centimeters.

What type of triangle did Pac-Man learn about?

• Equilateral

• Isosceles

• Right Angle

• Scalene

What was the length of the hypotenuse of the triangle?

• 30 centimeters

• 42 centimeters

• 72 centimeters

• 18 centimeters

What equation did Pac-Man derive from the perimeter of the triangle?

• X + y + 30 = 72

• X^2 + y^2 = 900

• X + y = 30

• X^2 + y = 72

What values did Pac-Man find for X after solving the equations?

• 18 and 24

• 30 and 42

• 24 and 30

• 18 and 30

How did Pac-Man find the value of y after determining X?

• By substitution

• By addition

• By multiplication

• By division
