Answer: The correct option is the second one.

Step-by-step explanation:

The graped equation is a vertical line in the point of x = -3.

The standard form of a equation is:

A*x + B*y = C

so here we will have that A = 1, B must be equal to zero and C = -3

1*x + 0*y = - 3

x = - 3

Then the correct option is the second one.

Which of the following is equal to the rational expression when x does not equal -3 x^2-9/x+3

mestny [16]

Answer:

x - 3

Step-by-step explanation:

Given

$\frac{x^2-9}{x+3}$

Note that x² - 9 is a difference of squares and factors as

x² - 9 = (x + 3)(x - 3), thus

$\frac{(x+3)(x-3)}{x+3}$

Cancel the x+ 3 factor on the numerator/ denominator leaving

x - 3 ← in simplified form

Jane took a piece of cardboard and cut out a triangle with measure 32°, 58°, and 90°, and side lengths 5 cm, 12 cm, and 13 cm. W

ioda

The answer is A. Right, Scalene.

This is because 90 degrees = a right angle

32 and 58 are smaller than 90, making it acute or scalene.
Isosceles means at least two sides are equal.
Equilateral means all sides are equal.

In this case, it is not isosceles or equilateral because the sides are not unequal.
It isn’t D. because that option doesn’t say “right”
