Question

Consider this expression: 7(10a+3b)

Answer 1

The answer could be 70a+21b

Answer 2

Answer: 70a + 21b

Step-by-step explanation:

By The Distributive Property, we can multiply a sum by multiplying each addend separately and then add the products,

That is, a(b+c) = ab + ac,

Here, the given expression is,

7 (10a + 3b),

By the above property,

We can write,

7 (10a + 3b) = 7 × 10a + 7 × 3b = 70a + 21b

Where, 70a and 21b are two different terms,

Thus, the required expression is 70a + 21b.
