only answer no solution its urgent plz fast

Answer 1

Answer:

4) 3×1+4×2 = 3+8 = 11

5)5= z+2

5-2 = z

3 = z

6)45+75+140+x = 360

260 +x = 360

x = 100

value of forth angle = 100

9) 11×p

10) 114÷16 = 7

48÷16 = 3

7:3

11) 7.82-3.95

= 3.87

12)

I) 6b^ 2 = cofficient of b^2 = 6

ii) -ab^2 = cofficient of b^2 = -a
