Which of the following expressions are equivalent to 48a^3-75a? Select all that apply.
Nadusha1986 [10]

Answer:

  • Answer 2) 3a(16a^2-25)
  • Answer 4) 3a(4a+5)(4a-5)
  • Answer 5) -3a(25-16a^2)
  • Answer 6) -3a(5-4a)(5+4a)

Step-by-step explanation:

The factors of each term are ...

  • 2·2·2·2·3·a·a·a
  • 3·5·5·a

So, the greatest common factor is 3a. Factoring that out gives ...

  3a(16a^2 -25) . . . . . . matches answer 2

The factor in parentheses is the difference of squares, so it can be factored. You have memorized the form for the difference of squares ...

  p^2 -q^2 = (p -q)(p +q)

so you know the factoring of this with p=4a and q=5 will be ...

  3a(4a -5)(4a +5) . . . . . . matches answer 4

__

Any <em>pair</em> of factors can be multiplied by -1 without changing the value of the expression. So, two more answers are equivalent:

   (-3a)(-(16a^2 -25) = -3a(25 -16a^2) . . . . . . matches answer 5

  (-3a)(-(4a -5)(4a +5) = -3a(5 -4a)(5 +4a) . . . . . . matches answer 6

Using radiclas, write equivalent expression for the expression y to the power of 2 1/3
SashulF [63]

Answer:

\large\boxed{y^{2\frac{1}{3}}=y^2\sqrt[3]y}

Step-by-step explanation:

y^{2\frac{1}{3}}\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=y^{2+\frac{1}{3}}=y^2\cdot y^\frac{1}{3}\\\\\text{use}\ a^\frac{1}{n}=\sqrt[n]{a}\\\\=y^2\sqrt[3]y

A segment with endpoints at $A(2, -2)$ and $B(14, 4)$ is extended through $B$ to point $C$. If $BC = \frac{1}{3} \cdot AB$, what
Mama L [17]

Answer:

  C = (18, 6)

Step-by-step explanation:

You have ...

  AB : BC = 1 : 1/3 = 3 : 1

  (B -A) / (C -B) = 3/1 . . . . . another way to write the distance relation

  B -A = 3(C -B) . . . . . . . . . multiply by (C-B)

  4B -A = 3C . . . . . . . . . . . add 3B

  C = (4B -A)/3 . . . . . . . . . divide by 3 to get an expression for C

  C = (4(14, 4) -(2, -2))/3 = (54, 18)/3

  C = (18, 6)
