When multiplying polynomials for a math
assignment, Alexis found the product to be
- 4x + 8x^2 - 2x^3 + 5. He then had to state the
leading coefficient of this polynomial. Alexis
wrote down -4. Do you agree with Alexis's
answer Explain your reasoning.

Determine the number of outcomes in the event. decide whether the event is a simple event or not. upper a computer is used to select randomly a number between 1 and 9 comma inclusive. event upper b is selecting a number greater than 4. event upper b has nothing outcome(s). is the event a simple event? (yes or no) because event upper b has (fewer than, exactly, more than) one outcome.

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers
