1. Find the value of the following algebraic
expressions given that m=6, n= 4 and p = 2.
(i) 3m-4n+2p (ii) 6n + Sp-7m
(iii) 11p + 12n-6m (iv) 5m - 6n-2p
Answers
Answer:
(i)
= 38
(ii)
= 70
(iii)
= 106
(iv)
= 58
Step-by-step explanation:
(i)
= (3 x 6) + (4 x 4) + (2 x 2)
= 18 + 16 + 4
= 38
(ii)
= (6 x 4) + (2 x 2) + (7 x 6)
= 24 + 4 + 42
= 70
(iii)
= (11 x 2) + (12 x 4) + (6 x 6)
= 22 + 48 + 36
= 106
(iv)
= (5 x 6) + (6 x 4) + (2 x 2)
= 30 + 24 + 4
= 58
