Mathematics

Airida [17]3 years ago
5 0

Answer:

(x - 4)

Step-by-step explanation:

Given x = a is a root then (x - a) is the corresponding factor

Given x = 4 is a root, then

(x - 4) ← is the corresponding factor

Note if x = - 4 is a root , then

(x - (- 4)), that is (x + 4) is the corresponding factor

Usando proporciones, se encuentra que 400 africanos han participado.

En total, hay x participantes.

\frac{5}{6} de los corredores son europeos, o sea:

E = \frac{5x}{6}

Los americanos son la dècime parte de los europeos, o sea:

Am = \frac{1}{10}E = \frac{5x}{60} = \frac{x}{12}

Los africanos son la quinta parte de los americanos, o sea:

Afr = \frac{1}{5}Am = \frac{x}{60}

En la carrera han inscritos 24 000 participantes, o sea, x = 24000. Por eso, la cantidad de africanos es:

Afr = \frac{x}{60} = \frac{24000}{60} = 400

The answer would be 42° because a triangle equals 180° and you know 2 angle measurements, 48 and 90.
48 + 90 = 138
180 - 138 = 42°
(You know one angle is 90° because supplementary angles equal 180°)
