0 because if u subtract the equations you get 0x + 0y = 14 which is not possible

Which of the following is the product

choli [55]

Answer:

$\text{\bf{A.}}\quad\dfrac{3x^2}{x^2-6x-7}$

Step-by-step explanation:

As with multiplying any rational expressions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.

$\dfrac{3x}{x+1}\cdot\dfrac{x}{x-7}=\dfrac{(3x)(x)}{(x+1)(x-7)}=\dfrac{3x^2}{x^2-6x-7}$

_____

The denominator product is found using the distributive property. Each of the terms of one factor is multiplied by the other factor.

$(x+1)(x-7)=x(x-7)+1(x-7)\\\\=x^2-7x+1x-7=x^2-6x-7$

Answer:

= 26,(6)

≈ 26,7

Step-by-step explanation:

C = 5/9(F - 32)

= 5/9(80 - 32)

= 5/9(48)

= 5×48/9

= 240/9

= 26,(6)

≈ 26,7

Find the quotient. 48j 5 k 2 ÷ (-3j 3 k) A) -16j2k B) -16j3k2 C) -16j3k

posledela

For this case we must find the quotient of the following expression:

$\frac {48 * j ^ 5 * k ^ 2} {- 3 * j ^ 3 * k} =$

We have to:

$\frac {48} {- 3} = - 16$

By definition of power properties we have:

$\frac {a ^ m} {a ^ n} = a ^ {m-n}$

So so:

$\frac {48 * j ^ 5 * k ^ 2} {- 3 * j ^ 3 * k} = - 16 * j ^ {5-3} * k^{2-1}=-16*j^2*k$

Answer:

see below

Step-by-step explanation:

The figure below shows the selections I would make.

You can choose "polygon similarity postulate" for the second blank based on that step's similarity to the one two steps down from it.

Strictly speaking, the distributive property is a property of multiplication over addition. It is not a property of equality.
