1.	Section-BQuestion numbers 9 to 14 carry 2 marks each.g. Is 7 × 5 x 3 × 2 +3 a composite number? Justify your answer.10. Can (a-2) be the remainder on division of a polynomial pec) by(2x+ 3)P Justify your answer.1In Fig. 3, ABCD is a rectangle. Find the values ofx and y.12Teacher asked the students, to find tan 0 if 7sin 20 +3cos 0-4. A1 s the answer correct? Tustify it.ー12Fig. 3
Answer» x+y = 12 x-y = 8 solvinv, we get 2x = 20, x = 10 10-y = 8 y = 10-8 = 2

Answer»

x+y = 12

x-y = 8

solvinv, we get

2x = 20, x = 10

10-y = 8

y = 10-8 = 2
