Question

Find the value of the following, if a=5, b = 2

i) a + 2b ii) 3a – b

10. Find the sum :- u + v, u – v, 2u + 5v, 2u – 5v

11. Subtract m + n from 3m – 7n.

12. Simplify : n + (m + 1) + (n + 2) + (m + 3) +(n + 4) + (m + 5)​

Answer 1

Step-by-step explanation:

I) 9 ii) 13

if u,v,m,n are same values of a,b respectively then the answers are

10)5+2+5-2+10+10+10-10=24

11) (15-14)-(5+2)=1-7=6

12) 2+(5+1)+(2+2)+(5+3)+(2+4)+(5+5)=36
