Ответ:

Пошаговое объяснение:

=(1-5/6)(2+5/6)+(3+5/6)(4+5/6)=1/6*17/6+23/6*29/6=17/36+667/6=684/6=114

Answer 2

To find the values of the expression (1-x)(2+x) + (3+x)(4+x) for x = 5 and x = 6, simply substitute the given values into the expression and perform the calculations.

Let's start with x = 5:

(1 - x)(2 + x) + (3 + x)(4 + x)

(1 - 5)(2 + 5) + (3 + 5)(4 + 5)

(-4)(7) + (8)(9)

-28 + 72

Result for x = 5: 44

Now, let's calculate for x = 6:

(1 - x)(2 + x) + (3 + x)(4 + x)

(1 - 6)(2 + 6) + (3 + 6)(4 + 6)

(-5)(8) + (9)(10)

-40 + 90

Result for x = 6: 50

So, the values of the expression for x = 5 and x = 6 are 44 and 50, respectively.
