The distributive property of multiplication is a very useful property that lets you simplify expressions in which you are multiplying a number by a sum or difference. The property states that the product of a sum or difference, such as 6(5 – 2), is equal to the sum or difference of the products – in this case, 6(5) – 6(2).
Remember that there are several ways to write multiplication. 3 x 6 = 3(6) = 3 • 6.
3 • (2 + 4) = 3 • 6 = 18.
Distributive Property of Multiplication over Addition
The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2.
3(10 + 2) = ?
According to this property, you can add the numbers and then multiply by 3.
3(10 + 2) = 3(12) = 36. Or, you can first multiply each addend by the 3. (This is called distributing the 3.) Then, you can add the products.
Answer:
The opposite number of +43 is -43 , I hope this is helpful :)
Answer:
200,000
Step-by-step explanation
10 x 2 is 10
So (8x100)x(2.5x100) is 200,000
8x100=800
2.5x100=250
800x250=200,000
Answer:
1.25π
Step-by-step explanation:
Hello There!
The area of a sector can be found using this formula
![A=\frac{0}{360} \pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B0%7D%7B360%7D%20%5Cpi%20r%5E%7B2%7D)
where 0 = angle and r = radius
so given the measures r = 3 and 0 = 50 all we have to do is plug in the values into the formula
so...
![A=\frac{50}{360} \pi 3^{2} \\3^{2}=9 \\\frac{50}{360} 9=1.25](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B50%7D%7B360%7D%20%5Cpi%203%5E%7B2%7D%20%5C%5C3%5E%7B2%7D%3D9%20%5C%5C%5Cfrac%7B50%7D%7B360%7D%209%3D1.25)
so the area of the sector = 1.25π
Note: it says to leave your answer in terms of pi so we do not have to apply pi
