ASAP PLEASE HELP!! “Find the quotient”

elena-14-01-66 [18.8K]

Answer:

The quotient is $\frac{x(2x-3)}{7}$ answer (D)

Step-by-step explanation:

$\frac{2x-3}{x}$ ÷ $\frac{7}{x^{2} }$

In division with fractions we reverse the fraction after division sign and change division sign to multiplication sine

$\frac{2x-3}{x}$ × $\frac{x^{2} }{7}$

$\frac{2x-3}{1}$ × $\frac{x}{7}$

$\frac{x(2x-3)}{7}$

Which expressions are equivalent to − 56 z + 28 −56z+28minus, 56, z, plus, 28? Choose 2 answers: Choose 2 answers: (Choice A) A

Dmitrij [34]

Answer:

$(D)-2(28z-14) \: and\:\\(E) -7(8z-4)$

Step-by-step explanation:

We are to determine which of these expressions are equivalent to: $-56 z + 28$

$(A)\frac{1}{2}\cdot(-28z+14) \\(B)(-1.4z+0.7)40\\(C)(14-7z)\cdot(-4)\\(D)(8z-4)(-7)\\(E)-2(-28z-14)$

$-56 z + 28$

If we factor out -2

$-56 z + 28=-2(\frac{ -56 z}{-2} + \frac{28}{-2})=-2(28z-14)$

If we factor out -7

$-56 z + 28=-7(\frac{ -56 z}{-7} + \frac{28}{-7})=-7(8z-4)$

Therefore, the two equivalent expressions are:

$-2(28z-14) \: and\: -7(8z-4)$
