42=-2d+6 I need help
sineoko [7]
<span>42=-2d+6

Here, to find d, you need to separate it on one side.
First, subtract 6 from both sides.

42-6 = -2d + 6 - 6
36 = -2d

Now divide both sides by -2.

36/-2 = -2/-2d
-18 = d

The answer to this problem is -18, or d = -18.</span>

Help please<br> I dont get this stuff
Lena [83]

Answer:

B) 3,375 / 3

Step-by-step explanation:

well, the way you find the volume of a cube is length * width * height. so, if you work backwards, then 3,375/3 = Length. (or width or height, since a cube is equal on all sides)  sorry for bad explanations I dunno how to put it-

Goodluck on your homework/schoolwork!

How would the expression x^2+27 be rewritten using sum of cubes?
nydimaria [60]
Assuming the square is not a typo, one can write


x^2+27=(x^{2/3})^3+3^3=(x^{2/3}+3)\bigg((x^{2/3})^2-3x^{2/3}+9\bigg)

=(x^{2/3}+3)\bigg(x^{4/3}-3x^{2/3}+9\bigg)
