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.
