Question

A=(3×7+2×17)×(91-4×20)+59

B=(7×7+15):(16-15:3+5)×7

C=(32-5×6):(7+2×10)×(49-30+5)

Answer 1

Bons estudos, abraços!!!

Answer 2

A)
= (3×7+2×17)×(91-4×20)+59
= (21+34).(91-80)+59
= 55.11+59
= 605+59
= 664

B)
= (7×7+15):(16-15:3+5)×7
= (49+15): (16-5+5).7
= 64:16.7
= 4.7
= 28

C)
=(32-5×6):(7+2×10)×(49-30+5)
= (32-30): (7+20).(19+5)
= 2: 27 . 24
= 0,074 .24
= 1,776
