Me with this problem:

combine like terms to create an equivalent expression.

6(.5w-.75)

! this is for a grade and i need the right answer or it will deprove my grade.

6*.5w = 3w

6 * .75 = 4.5

3w - 4.5 is the simplified answer.

step-by-step explanation:

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

i hope i you.
