Question

8(7+3в)-31 при в =2 52+4(11+в) при в=6

Answer 1

56+24b-31=24b-25 при b=2 24•2-25=23

52+44+4b=96+4b при b=6 96+4•6=96+24=120

Answer 2

To evaluate these expressions, we just need to substitute the given value of в and perform the arithmetic operations according to the order of operations (also known as PEMDAS or BODMAS).

For the first expression, when в=2:

8(7+3в)-31 = 8(7+3(2))-31 = 8(7+6)-31 = 8(13)-31 = 104 - 31 = 73

Therefore, the value of the first expression when в=2 is 73.

For the second expression, when в=6:

52+4(11+в) = 52+4(11+6) = 52+4(17) = 52+68 = 120

Therefore, the value of the second expression when в=6 is 120.
