Answer 1

Answer:

5 a - 7 b + b ^ 2 = -15

Step-by-step explanation:

Evaluation of the expression for a = - 1 and b = 5.  

5 a - 7 b + b ^ 2,

Putting the values in expression,

= 5 a - 7 b + b ^ 2,

= 5 ( - 1 ) - 7 ( 5 ) + ( 5 ) ^ 2,

= - 5 -35 + 25,

= - 40 + 25,

= -15

Answer 2

5 x (-1) - 7 x 5 + 5^2
-5 - 35 +25
-40 + 25
= -25
