There are several ways, but the general format follows f(x) = ax2 + bx + c f(x) = ax² + bx + c, where A, B, and C are non-zero numbers. Another way of finding a quadratic equation is examining the graph of it, you'll notice a "U" shape called a parabola, which come in many shapes but they all retain a "U"-like curve.

Answer:

Correct answer: x = 4

Step-by-step explanation:

If I saw your fractions right it's like this:

(2 + x) / (5 + x) = 2 / 3 => 3 (2 + x) = 2 (5 + x) => 6 + 3 x = 10 + 2 x

3 x - 2 x = 10 - 6 => x = 4

We will check

2 + 4 / 5+ 4 = 6 / 9

When we divide both numerator and denominator

with 3 we get 2/3

Answer:

Length of the shadow of player's sister is 5.25 feet.

Step-by-step explanation:

From the figure attached,

AB represents the basketball player and DE is his little sister.

Height of basketball player = 6.5 ft

Length of shadow of the player = 9.75 ft

Height of player's sister = 3.5 ft

Since, ΔABC and ΔEDC are the similar triangles, their corresponding sides will be proportional.

$\frac{AB}{DE}= \frac{ED}{DC}$

$\frac{6.5}{3.5}= \frac{9.75}{x}$

x = $\frac{9.75\times 3.5}{6.5}$

x = 5.25 ft

Therefore, length of the shadow of player's sister is 5.25 feet.
