Question

(5+B)^2+(7-B)*B при B=1\17

Answer 1

B^2 + 10b + 25 + 7b - b^2 = 
= 17b + 25

b= 1/17 ==> 17*1/17 + 25 = 1 + 25 = 26

Answer 2

To evaluate the expression (5+B)^2+(7-B)*B for B=1/17, we can substitute B=1/17 into the expression and simplify as follows:

(5+B)^2 + (7-B)*B       # Substitute B = 1/17
= (5 + 1/17)^2 + (7 - 1/17)*(1/17)
= (85/17 + 1/17)^2 + 6/289
= (86/17)^2 + 6/289
= 7396/289 + 6/289
= 7402/289
≈ 25.60967

Therefore, when B=1/17, the value of the expression (5+B)^2+(7-B)*B is approximately 25.60967.
