A(10) = <span>9(10) + 9= 90+9 =99
---------------------------------------------</span>
Sub the number in
19 + 4(4)
= 19 + 16
= 35
multiplication is first because of bedmas
Just combine like terms: (f+g)(x)=x^2+6x+30
The answer is $990. Because 0.36 times 2750=990
Answer:
0.10 or 10%
Step-by-step explanation:
Since each student must take at least 2 courses, if no student took all three courses, the sum of the percentages would total 200% (counting each student twice). Therefore, the proportion of students taking all three courses is the difference between the sum of all percentages and 200%:

0.10 or 10% of the students take all 3 courses.
