Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern. f(x) = 1.5x - 0.5x

f(x) = 1.5x^2 + 1.5x

f(x) = 1.5x^2 - 0.5v

f(x) = 0.5x^2 + 0.5x

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

answer: what statements

step-by-step explanation if you write the statements down then i could you.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
