4: A school has 314 boys & 310 girls. If they are to be grouped into equal classes of 26 each , how many classes will there be?
314 boys + 310 girls = 624
If they are grouped into classes of 26 students each, how many class will there be?
130 students = 5 classes
Therefore
260 students = 10 classes
260 x 2 = 520 = 20 classes
26 x 24 = 624
Number of classes = 24
Question 5).
Jim worked 48 weeks last year. Each week he worked 38 hours. If he worked an additional 240 hours of overtime, how many hours did he work in all?
Solution:
48 weeks
24hrs × 7 = 168hrs
168 x 48 = 8,064
Additional 240hrs
= 168hrs = 7 days (a week)
240hrs - 168 = 72 (3days)
168 + 72
= 240hrs + 8, 064
= 8, 304 hrs

Answer:
-6 because I did it on my calculator
Answer:
45x^3 + 123x^2 + 104x + 28
=(45x^3 + 60x^2 + 20x) + (63x^2 + 84x + 28)
=5x(9x^2 + 12x + 4) + 7(9x^2 + 12x + 4)
=(5x + 7)(9x^2 + 12x + 4)
=(5x + 7)(3x + 2)^2
=> Option D is correct
