Answer:
-9A · √(5yA)
Step-by-step explanation:
The coefficient -3 stays the same.
45 factors into 5·9, which is helpful because 9 is a perfect square.
Thus, √45 = 3√5.
y cannot be factored. It stays under the radical.
A³ can be factored into A² (a perfect square) and A.
Thus,
-3√(45yA³) = -3 · 3√5 · √y · A · √A, or
= (-3)(3)(A) · √(5yA), or
= -9A · √(5yA)
Answer:
the answer is C bc I guessed
Step 1: Assign variable for the unknown that we need to find.
Let x be the number of students in 7th grade.
Step 2: Using the given statement we need to set up an equation.
7.5% of number of students in 7th grade are absent. 9 students are absent.
Conclusion:
There are<em><u> 120 students</u></em> in 7th Grade
