Question

Evaluate the following algebraic expressions: *​

Answer 1

Answer:

(a) 34

(b) 13

Step-by-step explanation:

(a) If a = 2 and b = 10, then

2a + 3b = (2×2) + (3×10)

= 4+30 = 34

(b) If c = 4, d= -1, then

c^2 + d^2 + -cd = c^2 + d^2 - cd

= 4^2 + 1^2 - (4×-1)

= 16 + 1 -4

= 17-4

= 13
