Answer: 21

Step-by-step explanation:

N-\left(2\cdot \:7\right)=7

\mathrm{Remove\:parentheses}:\quad \left(a\right)=a

N-2\cdot \:7=7

\mathrm{Multiply\:the\:numbers:}\:2\cdot \:7=14

N-14=7

\mathrm{Add\:}14\mathrm{\:to\:both\:sides}

N-14+14=7+14

\mathrm{Simplify}

N=21

Answer:

N = 21

Step-by-step explanation:

N - (2 × 7 ) = 7                                {2 × 7 = 14}

N - 14 = 7

   + 14   +14

----------------------

N = 21

<em>Now we can substitute:</em>

21 - (2 × 7 )

21 - 14 = 7

<em>Hence, the answer is N = 21</em>

Solve: log2(x-4) = 4
defon

Answer:

D

Step-by-step explanation:

log₂(x-4) = 4

Undo the log by raising 2 to both sides:

2^(log₂(x-4)) = 2^4

x - 4 = 2^4

x - 4 = 16

x = 20

Answer D.

The following set of coordinates most specifically represents which figure? (−5, 6), (−1, 8), (3, 6), (−1, 4) (6 points) Paralle
Vladimir [108]

Answer:

Rhombus

Step-by-step explanation:

The given points are A(−5, 6), B(−1, 8), C(3, 6), D(−1, 4).

We use the distance formula to find the length of AB.

|AB|=\sqrt{(-1--5)^2+(8-6)^2}

|AB|=\sqrt{16+4}

|AB|=\sqrt{20}

The length of AD is

|AD|=\sqrt{(-1--5)^2+(6-4)^2}

|AD|=\sqrt{16+4}

|AD|=\sqrt{20}

The length of BC is:

|BC|=\sqrt{(-1-3)^2+(8-6)^2}

|BC|=\sqrt{16+4}

|BC|=\sqrt{20}

The length of CD is

|CD|=\sqrt{(-1-3)^2+(6-4)^2}

|CD|=\sqrt{16+4}

|CD|=\sqrt{20}

Since all sides are congruent the quadrilateral could be a rhombus or a square.

Slope of AB=\frac{8-6}{-1--5}=\frac{1}{2}

Slope of BC =\frac{8-6}{-1-3}=-\frac{1}{2}

Since the slopes of the adjacent sides are not negative reciprocals of each other, the quadrilateral cannot be  a square. It is a rhombus
