Riley used the distributive property to find the product of 37 and 24. Which expression

Viktor [21]

Answer:

The expression Riley could have used to find the product of the two numbers is 24 × (30 + 7).

Step-by-step explanation:

The distribution property for multiplication is:

$a\times (b+c)=a\cdot b+a\cdot c$

In this case we need to determine the product of 37 and 24.

Compute the product as follows:

$37\times 24=24\times (30 +7)$

$=(24\times 30)+(24\times 7)\\=720+168\\=888$

Thus, the product of 37 and 24 is 888.
