Answer:

Step-by-step explanation:

Using the altitude- on- hypotenuse theorem

(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse) , so

x² = 4 × (4 + 8) = 4 × 12 = 48 ( take square root of both sides )

x = $\sqrt{48}$ = $\sqrt{16(3)}$ = 4 $\sqrt{3}$ → A

Solve the equation<br> 13-4x=1-x

dem82 [27]

Add 4x to both sides and get
13 = 1 + 3x
12 = 3x [from subtracted 1 from both sides]
x = 4 [from dividing 3 from both sides]

therefore your answer would be x = 4

Answer:

Not proportional

Step-by-step explanation:

If x and y are proportional then the equation relating them is

y = kx ← k is the constant of proportionality

To determine if x and y are in proportion then k must be equal for all ordered pairs, that is

k = $\frac{y}{x}$
