Answer:

9

Step-by-step explanation:

Letting h be the height of the tower

15        h

-----  = ------

5           3

Using cross products

15*3 = 5h

Divide each side by 5

45/5 = 5h/5

9 = h

Answer:

Step-by-step explanation:

g(5)= (-5)^2 + 5(-2) - 4

Graph the function f(x)=(x+1)(x-2)
creativ13 [48]
F(x) = (x + 1)(x - 2)
f(x) = x(x - 2) + 1(x - 2)
f(x) = x(x) - x(2) + 1(x) - 1(2)
f(x) = x² - 2x + x - 2
f(x) = x² - x - 2
