Answer
There are 170 ways the student can answer the test.
Explanation
If there are 20 multiple-choice questions with 5 choices each, the student has 100 choices. The first question has 5 choices to pick from. The second has 5 as well. So does the third. Hopefully now you realize that you have to multiply the number of choices by the number of questions.
The same thing goes with the true/false questions. There are 2 choices for each true/false question, and there are 35 of those. 35×2 is 70. There are 70 ways to answer on the true/false questions.
Now combine the number of choices on the first part and the second part; 100+70 is 170.
The answer would be b and c
Answer: x³+2x²-15x
Step-by-step explanation:
1. Expand
(x²-3x)(x+5)
2. Use the FOIL method: (a+b)(c+d)=ac+ad+bc+bd
x³+5x²−3x²−15x
3. Collect like terms
x³+(5x²−3x²)−15x
4. Simplify
x³+2x²-15x
