Answer
35x
Work Step by Step
For real numbers a, b, and c, the associative property of multiplication holds that:
$(a \times b) \times c=a \times(b \times c)$
Therefore, for a=x, b=7, and c=5, the associate property of multiplication holds that:
$(x \times 7) \times 5=x \times (7 \times 5)$
This expression simplifies to $35 \times x$ or $35x$
