f(t)=\begin{cases}0&\text{for }t

\mathcal L_s\{f(t)\}=\displaystyle\int_0^\infty f(t)e^{-st}\,\mathrm dt
=\displaystyle\int_2^\infty(t^2-4t+8)e^{-st}\,\mathrm dt=\frac{2e^{-2s}}{s^3}+\frac{4e^{-2s}}s

Help Please.<br><br> If 7m - 3 = 53. What is the value of 11m + 2?
Pachacha [2.7K]

Answer:

90.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
