How do you write -4 2/7 as an improper fraction

-26/7

Step-by-step explanation:

I like to think of it as a multiplication and division problem I guess. You multiply the whole number by the denominator (-4 x 7=-28) and then add the numerator to the product (-28+2=-26) Therefore, the answer is -26/7.

If that makes any sense haha.

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.
