Evaluate the expression 4ab + 5bc when a = 2, b = - 6, and c = - 2.

Answer

Evaluate the expression

4ab + 5bc

when a = 2, b = - 6, and c = - 2.

To prove

As the expression given in the question be

4ab + 5bc

As given

a = 2, b = - 6, and c = - 2.

Put all the these values in the above expression.

= 4 * 2 * - 6 + 5 * - 6 * - 2

= - 48 + 60

= 12

Therefore the value of expression 4ab + 5bc be 12.

(when a = 2, b = - 6, c = - 2 be - 12)
