We've simplified each expression, we can clearly see that:
Expression 1:
\(160 - 48x\)
Expression 2:
\(160 - 48x\)
Expression 3:
\(-48x + 160\)
All three expressions are equivalent to one another, since each simplifies to the same combination of terms.
Therefore, the answer is option: A) Yes, the expressions are equivalent.

Let's examine each expression step by step to see if they are equivalent to the given expression
\(-16(3x-10)\).
**Expression 1:
\(8(9-6x+11)\)**
Simplify by distributing the 8 across each term inside the parentheses:

\[8 \cdot 9 - 8 \cdot 6x + 8 \cdot 11 = 72 - 48x + 88\]
Combine the constant terms:

\[72 + 88 = 160\]
Now, the expression is:

\[160 - 48x\]

**Expression 2:
\(15+(3)/(2)(-32x+120)-35\)**
Before distributing, simplify the constant terms outside the parentheses:

\[15 - 35 = -20\]
Now, distribute
\((3)/(2)\) across each term inside the parentheses:

\[(3)/(2) \cdot (-32x) + (3)/(2) \cdot 120 = -48x + 180\]
Now, the expression is:

\[180 - 48x - 20\]
Combine the constant terms:

\[180 - 20 = 160\]
So, the second expression becomes:

\[160 - 48x\]

**Expression 3:
\(-16(3x-10)\)**
Distribute the
\(-16\) across each term inside the parentheses:

\[-16 \cdot 3x + -16 \cdot (-10) = -48x + 160\]
So, the third expression is:

\[-48x + 160\]
Now that we've simplified each expression, we can clearly see that:
Expression 1:
\(160 - 48x\)
Expression 2:
\(160 - 48x\)
Expression 3:
\(-48x + 160\)
All three expressions are equivalent to one another, since each simplifies to the same combination of terms.
Therefore, the answer is:z
A) Yes, the expressions are equivalent.
