How do I round 0.3 to the nearest thousandth

0.3 is 3 tenths.

The order of "ths" is tenths, hundredths, thousandths.

Since there are no numbers after the 3, you simply have to add 2 zeros to make it 300 thousandths.

What is 12765x6748+6789

Every calculation with multiple operations must abide to BODMAS (Brackets, Other, Divide, Multiple, Addition, Subtraction)

Thus we would multiple first, giving us 86138220. Then we would add giving us: 86145009

Thus we would multiple first, giving us 86138220. Then we would add giving us: 86145009

You do multiplication first

12765 times 6748=86138220

then add

86138220+6789=86145009

12765 times 6748=86138220

then add

86138220+6789=86145009

What is the product of a+3 and −2a2+15a+6b2? −2a3+9a2+45a+24b2

−2a3+21a2+45a+24b2

−2a3+9a2+45a+6ab2+18b2

−2a3+21a2+45a+6ab2+18b2

Answer:

C

Step-by-step explanation:

Given

(a + 3)(- 2a² + 15a + 6b²)

Each term in the second factor is multiplied by each term in the first factor, that is

a(- 2a² + 15a + 6b²) + 3(- 2a² + 15a + 6b²) ← distribute both parenthesis

= - 2a³ + 15a² + 6ab² - 6a² + 45a + 18b² ← collect like terms

= - 2a³ + 9a² + 45a + 6ab² + 18b²

Answer:

c

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The solution set of n2 − 14n = -45 is [ ]

Answer:

n=5 n=9

Step-by-step explanation:

n^2 − 14n = -45

Add 45 to each side

n^2 − 14n +45 = -45+45

n^2 -14n +45 = 0

Factor the equation

What 2 number multiply to 45 and add to -14

-5*-9 = 45

-5+-9 = -14

(n-5) (n-9) =0

Using the zero product property

n=5 n=9

What does it mean for a product of factors to be expressed using exponents

Answer:

Step-by-step explanation:

Using exponents is an abbreviated form of repeated multiplication. That is, exponents are used to write a multiplication composed of several equal numbers in a more simplified way.

This is called power, and it is formed by the base, which is the number that is multiplying several times, and by the exponent, which is the number of times the base is multiplied.

For example: 5x5x5x5x5x5x5. You can see that the number 5 is multiplied many times, that makes it longer. This would be the basis. The number 5 is multiplied 7 times (7 being then the exponent), therefore you can express this multiplication as:

Exponent is the expression in where you convert product factor expression into a shorter expression. So really you use it to make the question simpler and shorter(easier to understand).
