38 mm to m

38 mm * (0.001 m / 1 mm)
**cancel mm units**
38 * (0.001 m / 1)
0.038 m

you're correct

Fill in the missing numbers to complete the pattern 615,605,595

Sophie [7]

We are given pattern 615,605,595.

Let us check differences of second term - first term and

Third term - second term

Second term - first term = 605 - 615 = -10.

Third term - second term = 595 - 605 = -10.

So, each time 10 is being subtracted from previous term.

So, the sequnace would be

Find the roots of the following equations. a) 4x+9=34 b) (x-4)(x+2)=0 c) 2x^2-6x+4=0

Masteriza [31]

A. 4x + 9 = 34
 - 9 - 9
 4x = 25
 4 4
 x = 6.25

B. (x - 4)(x + 2) = 0
 x - 4 = 0 U x + 2 = 0
 + 4 + 4 - 2 - 2
 x = 4 x = -2

C. 2x² - 6x + 4 = 0
 2(x²) - 2(3x) + 2(2) = 0
2(x² - 3x + 2) = 0
 2 2
 x² - 3x + 2 = 0
 x = -(-3) +/- √((-3)² - 4(1)(2))
 2(1)
 x = 3 +/- √(9 - 8)
 2
 x = 3 +/- √(1)
 2
 x = 3 +/- 1
 2
 x = 3 + 1 U x = 3 - 1
 2 2
 x = 4 x = 2
 2 2
 x = 2 x = 1
