6(3x + 3) - 3(4x - 2)<br> -<br> Please help expand and simplify

Dimas [21]

Answer:

The answer is 3(2x + 3)

Step-by-step explanation:

6(3x + 3) - 3(4x – 2)

Multiply (3x + 3) by 6 and (4x – 2) by (-3) we get,

6 (3x + 3) = 18x + 3

(-3) (4x – 2) = -12x + 6

Now, Simply

18x + 3 – 12x + 6

6x + 9 = 3(2x + 3)

Thus, The answer is 3(2x + 3)

Which of these measurements is expressed to four significant figures?

Reil [10]

Answer: The answer is d. 16.530 m with 4 significant figures

Step-by-step explanation:

Significant figures are the digits that contribute meaning in the expression

In the given options

a. $2.6\times 10^4$

Here only 2 and 6 are counted as significant digits

b. $5.300\times 10^{-7}$

Here Since the zeros are after decimal So they will not be counted in significant figure i.e. S fig =2

c. 0.108

Here No of significant figures will be 3

d. 16.530

Here the no of significant figures are 4 i.e 1 6 5 3

So the answer is d.16.530
