Evaluate 8a+3b-10+c^2when a = 2, b=5, and c=4

8a+3b-10+c^2when a = 2, b=5, and c=4:

(8) (2) + (3) (5) - 10+42

=16 + (3) (5) - 10+42

=16+15-10+42

=31-10+42

=21+42

=21+16

=37

8a+3b-10+c^2 when a=2, b=5, c=4

Plug in numbers for variables:

8 (2) + 3b-10+c^2 (plug in 2 for a)

8 (2) + 3 (5) - 10+c^2 (plug in 5 for b)

8 (2) + 3 (5) - 10+4^2 (plug in 4 for c)

Evaluate:

8 (2) + 3 (5) - 10+4^2

8 (2) + 3 (5) - 10+16 (exponents)

16+3 (5) - 10+16 (multiplication)

16+15-10+16 (multiplication)

32-10+16 (addition)

22+16 (subtraction)

38 (addition)

Sorry if I messed up. It's hard to keep track of my work without paper because I'm not tech savvy but I'm pretty sure my answer is fine.

Best of luck!
