inez waters her plants every two days she trim them every 15 days she did both today when will she do both again
lord [1]


She will do both again in 30 days. 

She waters every two days and 2 is a even number.

She trims her plants every 15 days and 15 is an odd number.

When you add two odd numbers you get an even 15 + 15 = 30

Find f'(x) for f(x) = −8x^2 − 5x − 4.
zmey [24]
D/dx of -8x^2 - 5x - 4

So, use the power rule: -8 * d/dx (x^2) this means (x^n)' = n * x^n-1

So -8*2x

-5 * d/dx (x) = -5 * 1

So -5

d/dx of 4 is 0, because 4 is a costant.

Final result

-16x - 5
