If these are the missing parts: 

What is the quadrilateral?

a.rhombus
b. rectangle
c. trapezoid
<span>d. square

The quadrilateral formed by the </span><span>two equilateral triangles taped together is A. RHOMBUS.

Rhombus has equal sides but its is different from a square because it looks like a diamond.

Solve rational inequality x²+x-6/x²-3x-4≤0?​

Answer:

Step-by-step explanation:

x

=

(

x

)

(

x

)

Each of the linear factors occurs precisely once, so the sign of the given rational expression will change at each of the points where one of the linear factors is zero. That is at:

x

=

−

3

,

−

1

,

2

,

4

Note that when

x

is large, the

x

2

terms will dominate the values of the numerator and denominator, making both positive.

Hence the sign of the value of the rational expression in each of the intervals

(

−

∞

,

−

3

)

(

−

)

,

(

,

(

,

4

)

and

(

4

,

∞

)

follows the pattern

+

−

. Hence the intervals

(

−

3

,

−

1

)

and

(

2

,

4

)

are both part of the solution set.

When

x

=

−

1

or

x

=

4

, the denominator is zero so the rational expression is undefined. Since the numerator is non-zero at those values, the function will have vertical asymptotes at those points (and not satisfy the inequality).

When

x

=

−

3

or

x

=

2

, the numerator is zero and the denominator is non-zero. So the function will be zero and satisfy the inequality at those points.

Hence the solution is:

x

∈

[

−

3

,

−

1

)

∪

[

2

,

4

)

Which set of numbers CANNOT represent the lengths of the sides of a triangle?
posledela

Answer:

C

Step-by-step explanation:

The general rule is that any 2 must exceed the third in order for a triangle to form. If any one is an exception, it won't work.

A will form a triangle. Any 2 exceeds the third.

B also forms a triangle. Same rule.

C  does not work. 7 + 11 = 18 which is the value of the third leg.

D words Any two exceeds the 3rd.
