1.) 5 x 7 – 6 /2 + 3^2
= 5 x 7 – 6/2 + 9
= 35 – 3 + 9
= 32 + 9
= 41
2.) P = 2s + 2(s + 3) solve for s = 5
= 2 (5) + 2( 5 + 3)
= 10 + 2 ( 8 )
= 10 + 16
= 26

3.) 8 [ 6^2 – 3 (2 + 5) ] / 8 + 3
= 8 [ 6^2 – 3 (7) ] / 8 +3
= 8 [ 36 – 3 (7) ] / 8 + 3
= 8 [ 36 – 21] / 8 + 3
= 8 [ 15 ] / 8 + 3
= 120 / 8 + 3
= 15 + 3
= 18
