Can someone help me out?
2. Evaluate the expression for a = –1 and b = 5. Show your work.
5a – 7b + b^2
This is how i solved it i'm just seeing if i did it right or if i messed up somewhere throughout the problem
5+ 1 7(5) + (5)^2
35 25
4+ 35 25
4+ 35 = 31
31+ 25 = 6

Best ResponseYou've already chosen the best response.1So simply just plug in the numbers: \(\sf\Large 5(1) 7(5)+(5)^2=?\)

Best ResponseYou've already chosen the best response.0Alright is this correct 5+( 1) 7(5) + (5)^2 35 25  5 35 25 5+ 35 = 40 40+ 25 = 15

Best ResponseYou've already chosen the best response.1almost correct, but \(\sf\Large 40+25 = \color{red}{}15\) because \(\sf\Large 40+25 = 2540\)

Best ResponseYou've already chosen the best response.05+( 1) 7(5) + (5)^2 35 25  5 35 25 5+ 35 = 40 25 + 40 = 15 How about now?

Best ResponseYou've already chosen the best response.1you have all the steps correct except the last one \(\sf\Large 25+ (40) = 15\) \(\sf\Large 40 + 25 = 15\) It's \(\bf \color{red}{}\)15 It's a negative 15...
