6(x + 3) − 3 = 39 whats the solution of x?

x = 4

Step-by-step explanation:

6(x+3)-3= 39

6x+18-3 =39

6x+15 =39

   -15   -15

6x= 24

/6     /6

x=4

x=4

Step-by-step explanation:

Do distributive property

6(x + 3) − 3 = 39(multiply 6 by all the numbers in the brackets)

6x+18=39 (subtract 18 on both sides)

6x=24 (divide 6 on both sides)

x=4

so, converting firstly the mixed fractions to improper fractions and then "adding".

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
