Question

(3-b)*5 раскрыть скобки 6m(7n+8p)

Answer 1

Пошаговое объяснение:

(3-b)*5=15-5b

6m(7n+8p)=42mn+48mp

Answer 2

To expand the expression (3-b)*5, we can apply the distributive property, which states that multiplying a number by a sum is the same as multiplying the number by each term in the sum and then adding the results.

Let's expand (3-b)*5:

(3 - b) * 5 = 3 * 5 - b * 5 = 15 - 5b

So, the expression (3-b)*5 expands to 15 - 5b.

Now, let's expand the expression 6m(7n+8p):

6m(7n + 8p) = 6m * 7n + 6m * 8p

Applying the distributive property to each term, we get:

6m * 7n = 42mn 6m * 8p = 48mp

Putting it together, the expanded form of 6m(7n + 8p) is:

42mn + 48mp.
