Answer:

D. 7n = 28

Step-by-step explanation:

$6+n=24\\ 6+4=24\\ 10\neq 24\rightarrow \text{Incorrect!}$

$5n=54\\5(4)=54\\20\neq54\rightarrow\text{Incorrect!}$

$12-n=16\\12-4=16\\8\neq16\rightarrow\text{Incorrect!}$

$7n=28\\7(4)=28\\28=28\rightarrow\text{Correct!}$

Therefore the answer is D

Answer:

There are four correct expressions.

Step-by-step explanation:

Four correct expressions:

${x}^{2} - x - 42$

${x}^{2} +6x −7x −42$

$x(x−7)+6(x−7)$

$2x +6x-7x−42$

Simplify:

${x}^{2} - x - 42$

$(x+6)(x−7)$

$x(x−7)+6(x−7)$

$2x +6x-7x−42$

${x}^{2} −7x+6x−42$

${x}^{2} - x - 42$
