Sagot :

To solve the multiplication [tex]\(15 \times 14\)[/tex], we can break it down step by step.

First, we write out the multiplication in its full form:

[tex]\[ 15 \times 14 \][/tex]

We can also think of 14 as [tex]\(10 + 4\)[/tex]. So, we can use the distributive property to break it down:

[tex]\[ 15 \times (10 + 4) \][/tex]

Using the distributive property [tex]\(a(b+c) = ab + ac\)[/tex], we can separate it into two simpler multiplications:

[tex]\[ 15 \times 10 + 15 \times 4 \][/tex]

Next, we solve these two multiplications:

[tex]\[ 15 \times 10 = 150 \][/tex]
[tex]\[ 15 \times 4 = 60 \][/tex]

Now, add these results together:

[tex]\[ 150 + 60 = 210 \][/tex]

Thus, the product of [tex]\(15 \times 14\)[/tex] is:

[tex]\[ 210 \][/tex]

Therefore, the best answer to the question is:

A. 210
