Question

if a=1 b=2 and c=-2. find the value of
1. (7a+2b) c+6
2. 5b+2a-(6a-c)​

Answer 1

Answer:

1. 88 and 2. 5

Step-by-step explanation:

1. (7a+2b) c+6 = (7*1+2*2) 2+6

= (7+4) 8 = 11*8

= 88

2. 5b+2a-(6a-c) = 5*1+2*2-(6*1-2)

= 5+4-4= 5+0

=5

Answer 2

Answer:

Given, a=1 b=2 and c=-2

Now,

1. (7a+2b) c+6

= (7x1 + 2x2) x (-2) +6

= (7+4)x(-2) +6

= 11x-2 +6

= -22+6

= -16

2. 5b+2a-(6a-c)

= 5x2+2x1 -{6x1-(-2)}

= 10+2-(6+2)

=12-8

=4
