Given that AB parallels QR, AB bisects AE, QR bisects QT
enyata [817]

Answer:

  1. Dilate ΔABE by a factor of 2/5 to make ΔA'B'E'

  2. Translate A' to Q

Step-by-step explanation:

We notice the triangles have the same orientation, so no reflection or rotation is involved. The desired mapping can be accomplished by dilation and translation:

  1. Dilate ΔABE by a factor of 2/5 to make ΔA'B'E'

  2. Translate A' to Q

The result will be that ΔA"B"E" will lie on top of ΔQRT, as required.

Factorise 3x^3 - 12xy^2​
igomit [66]

Answer:

we can conclude that:

3x^3\:-\:12xy^2=3x\left(x+2y\right)\left(x-2y\right)

Step-by-step explanation:

Given the expression

3x^3-12xy^2

Let us factorize the expression

3x^3-12xy^2

Apply the exponent rule: a^{b+c}=a^ba^c

3x^3\:-\:12xy^2=3xx^2-12xy^2

Rewrite 12 as 4 · 3

                     =3xx^2-4\cdot \:3xy^2

Factor out the common term 3x

                     =3x\left(x^2-4y^2\right)

\mathrm{Apply\:Difference\:of\:Two\:Squares\:Formula:\:}x^2-y^2=\left(x+y\right)\left(x-y\right)

                      =3x\left(x+2y\right)\left(x-2y\right)

Therefore, we can conclude that:

3x^3\:-\:12xy^2=3x\left(x+2y\right)\left(x-2y\right)

De 50 estudiantes 30 aprobaron la asignatura de ciencias. ¿Que porcentaje de las estudiantes reprobaron la asignatura?
alexdok [17]

Answer:

El 40% de los estudiantes reprobaron la asignatura.

Step-by-step explanation:

Dado que sabes el número total de estudiantes y cuántos aprobaron la asignatura, puedes restar el número de estudiantes que aprobaron del total de estudiantes para encontrar los estudiantes que reprobaron la asignatura:

50-30=20

Ahora puedes calcular el porcentaje dividiendo el número de estudiantes que reprobaron entre el total de estudiantes y multiplicando el resultado por 100:

20/50*100=40%

De acuerdo a esto, la respuesta es que el 40% de los estudiantes reprobaron la asignatura.
