Answer:
9
Step-by-step explanation:
Whatever you do to the denominator, you've got to do to the numerator, and vice versa. So for 8 to become 24, you multiply by 3. do that to the numerator 3 as well. 3 × 3 is 9.

Answer: n > 6.85
Step-by-step explanation: So the orignal question was 13 < 4n – 14.4 and you want to know how to solve it.
13 < 4n – 14.4
27.4 < 4n (You add 14.4 to both sides to get n by itself)
27.4/4 < 4n (You divide both sides by 4 to get just n)
6.85 < n (This is because 27.4/4 is 6.85)

Answer:
x=2
Step-by-step explanation:
Primero, necesitamos calcular <<a>>
Sabemos que AD=BC y AB=CD porque lados opuestos congruentes
Entonces, vamos a calcular <<a>>.
Usamos AD y BC
2a-1=4a-15
suma 15 a ambos lados
2a+14=4
añada 2 en ambos lados
14=2a
divida
7=a
Ahora, usamos esta información para calcular <<x>>
Usamos CD=AB
2a-8=4x-2
pero sabemos que <<a>> es 7
entonces:
14-8=4x-2
6=4x-2
8=4x
2=x
<<x>> es 2

What's the question?
(if its x-intercepts, its 1,-2,-5 since you use the zero product property)
