Simplify the expression (1 - 5t) (-8) =

webb it

Step-by-step explanation:

-8+40t

Step-by-step explanation:

You can solve this by distributing the -8 to both the 1 and -5t. Distributing the -8 to the 1 would get you -8, and distributing it to the -5t would get you 40t, as two negatives multiplied together make a positive.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm
