A quadratic equation is one in which the highest exponent of x is 2.

is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic. The highest exponent of x is 3, not 2.
5x-7=0 is NOT quadratic. The highest exponent of x is 1, not 2.
x²+3x-5=0 is quadratic; the highest exponent of x is 2.
x-5=9x+7 is NOT quadratic. The highest exponent of x is 1, not 2.
x²-x=3x+7 is quadratic; the highest exponent of x is 2.

Answer:
Step-by-step explanation:
Multiply the numbers on each face 5×7, 6×7, 6×4÷2 (for the triangle) remember that there are 2 of each of the faces so the answer to 5×7 multiply that by 2 to get both faces
