Write a two-column (T) proof:
If -4(x-3)+5x=24, then x=12

you need to show us the graph.

step-by-step explanation:

it would open into a square depending on the type of envelope i’m not sure about the second part

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.

answer is (b.
