Answer:

Option D (There is no solution) is the correct answer.

Step-by-step explanation:

According to the question, the matrix is:

⇒ \left[\begin{array}{ccc}1&-5&-4\\0&0&7\end{array}\right]

The linear equation will be:

⇒ x-5y=-4

and

⇒ 0.x+0.y=7

i.e,

                0=7 (Not possible)

Thus the above given matrix has no solution. So the above is the correct option.

Which equation is an identity?
miskamm [114]

Answer:

D

Step-by-step explanation:

To be an identity we require both sides of the equation to equate

A

8x + 9 ≠ 8x - 3 ← not an identity

B

7x - 2 = 8x + 4 - x = 7x + 4 ≠ 7x - 2 ← not an identity

C

11 - (2x + 3) = 11 - 2x - 3 = - 2x + 8 ≠ - 2x - 8 ← not an identity

D

5x + 8 - x = 6x - 2(x - 4), that is

4x + 8 = 6x - 2x + 8 = 4x + 8 ← both sides equate thus an identity

The Westside dog kennel is Building a circular dog park the length of the fence around the park is approximately 110 feet how mu
vredina [299]
You are basically looking to find the area of a circle 
so to find the area of a circle the formula is  A=pi R sqr
so if you take the radius which is half of the diameter 110 you get 55
you multiply 55*55 and get 3025
you than multiply that by pie and get 
9503.32 if you round
