Answer:
.
Step-by-step explanation:
.
Answer:
42x² - 3x - 9
the area of the garden is:
(7x + 3)(6x - 3)
= 42x² - 21x + 18x - 9
= 42x² - 3x - 9
Total no. of students - 140 students
Total no. of students from all schools= 140+70+35+105=350
school A= 140÷350×100=40./. (multiplying by 100 because it's the total percentage )
School B = 70÷350×100=20./.
School C = 105÷350×100=30./.
School D = 105÷350×100= 10./.
Consisting all the schools percentage it gives 100./.
Hope this helps
