Step-by-step explanation:
I did this lesson in 4th grade
After one of them is chosen for 1st, there are only 9 choices for 2nd, and then there are only 8 choices for 3rd... and so on. There are 720 different ways to pick 1st, 2nd, and 3rd place from among 10 original students
Answer:
(a + 9)(a - 5)
Step-by-step explanation:
Given
a² + 4a - 45
Consider the factors of the constant term (- 45) which sum to give the coefficient of the a- term (+ 4)
The factors are + 9 and - 5 , since
9 × - 5 = - 45 and 9 - 5 = 4 , then
a² + 4a - 45 = (a + 9)(a - 5) ← in factored form
