Answer : B and C

Explanation :

firstly, we should know the definition of square matrix. It is a matrix in which number of rows is equal to number of columns

In case of A : it is given that several number of airlines  and several number of columns

if we consider the case of more number of airlines say 5 and we have only 4 cities that these 5 airlines offer services to. Then it will not  form a square matrix

NOTE: it would have formed the square matrix if there would have been equal number of airlines and  cities.

In case of  B: in this case we will have equal number of members in each team.

In case of C : in this case we are given with equal number of  equations and unknowns

In case of D: in this case we have augmented matrix which is formed by appending the column of the matrices given so it can never form a square matrix.

All the angles inside a quadrilateral add to 360 degrees.
But first, we should solve for x
Opposite angles add up to 180 degrees.
So we'll use angles B and D
x + 10 + x + 24 = 180
combine like terms
2x + 34 = 180
subtract 34 from both sides
2x = 146
divide both sides by 2
x = 73

Now let's solve for the angles
Angle D: x + 24 = 97
Angle B: x + 10 = 83
Angle A: x + 15 = 88

Opposite angles add up to 180
we know that angle A is 88
C + 88 = 180
subtract 88 from both sides
C = 92

Hope this helps!

DF bisects EDG Find FG. The diagram is not to scale.<br><br>A.15<br>B.14<br>C.19<br>D. 28​
Ahat [919]

Answer:

○ b. 14

Step-by-step explanation:

Since <em>DF</em><em> </em>is a segment bisector, set both expressions equal to each other:

3n - 4 = n + 8

-3n - 3n

__________

−4 = −2n + 8

-8 - 8

_________

−12 = −2n

__ ___

−2 −2

6 = n [Plug this back into both expressions above to get the value of 14]; 14 = FG; 14 = EF

I am joyous to assist you anytime.
