Distribute (2m-5m)(-5)

Mathematics
1 answer:
Reika [66]3 years ago
6 0

First Method (Distributive Property)

(2m - 5m) (-5)

Rearrange the equation to make it easier.

(-5) (2m - 5m)

In distributive property, it's all about multiplying. The -5 goes to the 2m and the 5m. Like this: (-5 • 2m) - (-5 • 5m).

-10m + 25m

15m

Second Method

(2m - 5m) (-5)

Since 2m and 5m have the same variable, we can subtract them.

(-3m) (-5)

Multiply.

15m

15m is your answer. I hope this helps!

What is theoretical probability of rolling a number greater than 4 on a standard number cube
sergeinik [125]
So cube faces were numbered 1, 2, 3, 4, 5 and 6.

There are 6 faces in total and there are two faces greater than 4 (face 5 and 6).

So that would be (desired outcomes) / (total outcomes) = 2 / 6 = 1/3

So theoretical probability of rolling a number greater than 4 is 1/3.

Hope this helps.

Which is the product?
Luda [366]

Question:

Iliana multiplied 3p – 7 and 2p^2 – 3p – 4. Her work is shown in the table.

Which is the product?

6p^3 + 23p^2 + 9p + 28

6p^3 – 23p^2 – 9p + 28

6p^3 – 23p^2 + 9p + 28

6p^3 + 23p^2 – 9p + 28

Answer:

Option C: 6 p^{3}-23 p^{2}+9 p+28 is the correct answer.

Explanation:

The two expressions are 3 p-7 and \left2 p^{2}-3 p-4\right

The product of the expression can be determined by multiplying each of the first term with the second term of the expression, we get,

(3 p-7)\left(2 p^{2}-3 p-4\right)

3 p \cdot 2 p^{2}+3 p(-3 p)+3 p(-4)+(-7) \cdot 2 p^{2}+(-7)(-3 p)+(-7)(-4)

Simplifying we have,

6p^3-9p^2-12p-14p^2+21p+28

Adding the like terms, we have,

6 p^{3}-23 p^{2}+9 p+28

Thus, the product of the two expression is 6 p^{3}-23 p^{2}+9 p+28

Hence, Option C is the correct answer.
