ANSWER

EXPLANATION
The given function is:

and



To find g(f(-1)), we substitute x=-1, to obtain;

We simplify the square in the denominator to get,

We now add the denominator to obtain;

3 divided by 1 quarter is equal to 12 because
3 divided 1/4 is 12 . 1/4 is a quarter. so this is how you get your answer. 3 divide 1/4 = 3/1 multiply 4/1=12/1 =12

Answer:
The generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
Step-by-step explanation:
We are given the following from what she knows
m∠3=2⋅m∠1... 1
m∠2=2⋅m∠4 ... 2
m∠2+m∠3=360 ... 3
From what is given, we can substitute equation 1 and 2 into equation 3 as shown:
From 3:
m∠2+m∠3=360
Substituting 1 and 2 we will have:
2⋅m∠4 + 2⋅m∠1 = 360
Factor out 2 from the left hand side of the equation
2(m∠4+m∠1) = 360
Divide both sides by 2
2(m∠4+m∠1)/2 = 360/2
m∠4+m∠1 = 180°
Since the sum of two supplementary angles is 180°, hence the generalisation she can make from her work is that the other two angles of the quadrilateral are supplementary i.e their sum is 180°
