Answer:
Step-by-step explanation:
No of students study math = 3/5 of 50 = 30
No of students study English = 3/10 of 50 = 15
Total = 30 + 15 = 45
Remaining students = 5
No of students study geography = 5
Fraction of geography to whole class = 5/45 = 9
9.66 - you just multiple 6 by 1.61
-x^2 + 4x + 12 = -3x + 24
-> x^2 - 7x + 12 = 0
-> (x-3)(x-4) = 0
-> x= 3 or 4
so y = 15 when x = 3, y = 12 when x = 4
Answer:
(x+3)(x-4)^2
Step-by-step explanation:
= (x+3)(x^3-5x^2-8x+48)/(x+3)
= x (x^3-5x^2-8x+48)/(x+3)
= x^2-8x+16
= (x+3)(x-4)(x-4)
= (x+3)(x-4)^2
