One third kaylee's age increased by 12 is equal to twice her age decreased by 3. how old is kaylee?
andreyandreev [35.5K]
I would think Kaylee is 5 since 12 divided by 3 is 4 and 4 * 2 is 8, and 8-3 is 5. So, I would think Kaylee is 5.

Resolver xfa... El taller trata de division de polinomios o algo asi
luda_lava [24]

La altura del triangulo está dada por el polinomio:

p(x) = a + 4

<h3></h3><h3>¿Cual es la altura del triangulo?</h3>

Recordar que para un triangulo de base B y altura H, el area es

A = B*H/2

En este caso, sabemos que la base es B = (4*a^2 + 6)

Y el area es A = 2a^3 + 8a^2 +3a +12

Entoces la altura será un polinomio tal que:

P(a)*(4*a^2 + 6)/2 = 2a^3 + 8a^2 +3a +12

P(a)*(4*a^2 + 6) = 2*(2a^3 + 8a^2 +3a +12) = 4a^3 + 16a^2 + 6a + 24

Podemos ver que p(a) va a ser un polinomio de grado 1, entonces:

p(a) = (c*a + b)

Reemplazando eso:

(c*a + b)*(4*a^2 + 6) = 4a^3 + 16a^2 + 6a + 24

Expandiendo:

(4c)*a^3 + (6c)*a + (4b)*a^2 + 6*b = 4a^3 + 16a^2 + 6a + 24

Comparando terminos del mismo exponente, podemos ver que:

(4c) = 4

6c = 6

4b = 16

6b = 24

Resolviendo esas ecuaciones para c y b, podemos ver que:

b = 16/4 = 4

c = 4/4 = 1

Entonces la altura del triangulo está dada por el polinomio:

p(x) = a + 4

write an equation: Great Uncle Wilbert splits his inheritance equally between his five nieces and nephews. Unfortunately each of
Vaselesa [24]
I think it would be 1225000 because:

$7,500 each to the govt each comes out to $37,500 total given 
237,500 each to the kids comes out to 41,187,500 total given 
so adding both totals, you get $1,225,000 total money in Great Uncle Wilbert's inheritance

apparently he was rich xD
