The sum of 5 times a number and 4 is -9

The sum of 5(x) + 4 = (-9)

We have to isolate the x so we subtract 4.

5(x) + 4 = (-9)

5(x) - 4 = - 4

5(x)  = (- 13)

Now we have to continue to isolate the x.

So now we have to divide by 5.

5(x)/5 = (-13)/5

and that's x = (-2.6)

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
