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)

Daniel made 6 out of 15 free throw shots. About how many out of the next 10 free throw shots would you expect him to make
mixer [17]
6÷15= 0.4= his percentage at the line
0.4×100%= 40%
(x represents how much he makes in 10 shots) x/10 = 40/100 (Percent from the line)
cross multiply 100x=400
isolate x 
100x÷100= 400÷100 
x=4
I predict that daniel will make 4 shots out of ten
