Answer:
Choice C
Step-by-step explanation:
x^2 +6x+8
what numbers multiply together to make 8 and add together to make 6
4*2 = 8 4+2 =6
(x+2) (x+4)
Choice C
Answer:

Step-by-step explanation:
Given





Required
Find the constant of variation
From the question, the variation is as follows



Convert variation to equation

Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t


Divide both sides by p



Substitute the values of p, r, s and t in the above equation


Divide numerator and denominator by 6

Hence, the constant of variation is; 
Answer:
220
Step-by-step explanation:
Answer:
∠DFE=119°
Step-by-step explanation:
step 1
Find the measure of angle BFD
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite.
so
∠BFD=(1/2)[arc BD+arc CE]
substitute the given values
∠BFD=(1/2)[38°+84°]
∠BFD=61°
step 2
Find the measure of angle DFE
we know that
∠BFD+∠DFE=180° -----> linear pair (supplementary angles)
substitute
61°+∠DFE=180°
∠DFE=180°-61°=119°
