One of the greatest strengths of behavioral psychology is the ability to clearly observe and measure behaviors. Weaknesses of this approach include failing to address cognitive and biological processes that influence human actions.
Right away we see that expressions (a), (b), and (d) are equivalent, since addition is commutative: $2x + 8 = 8 + 2x$. We now only have to check (c) and (e). If $x=0$, (c) and (e) have the value 4, whereas (a), (b), and (d) have the value 8.So (c) and (e) are not equivalent to (a), (b), and (d).Moreover, if $x=1$, then (c) has the value 6 and (e) has the value 5, so those two expressions are not equivalent either.For (c), we can use the distributive property and decompose one of the numbers to write two equivalent expressions: $$ \begin{align} &2x+4 \\ &2(x+2) \\ &2(x+1+1) \end{align} $$.o (c) and (e) are not equivalent to (a), (b), and (d). Moreover, if $x=1$, then (c) has the value 6 and (e) has the value 5, so those two expressions are not equivalent either. For (c), we can use the distributive property and decompose one of the numbers to write two equivalent expressions:
Consecutive means one after another.   If the first is a, then the second is a+1.   The sum of these is   a + a + 1 = 2a+1 = -377   2a = -378   a = -189  â¦    So the two numbers are -189 and -188.The integers are 43 and 44.The answer can be found by representing the two consecutive numbers as n and n+1.onsecutive means one after another.   If the first is a, then the second is a+1.   The sum of these is   a + a + 1 = 2a+1 = -377   2a = -378   a = -189  â¦    So the two numbers are -189 and -188.
