Step-by-step explanation:
- 4 and 1 are roots.
Therefore, (x + 4) & (x - 1) are factors and 5 is leading coefficient.
Therefore, required quadratic equation is:

B is a variable that is as far as it can be solved
I believe the answer is C.
Answer:
ABCD is a parallelogram/Given
Line AB is parallel to line DC/Opposite sides of a parallelogram are equal
Line FD is congruent to Line FD/Reflexive property
Line BE is congruent to line BE/Reflexive property
Line AC is congruent to Line AC/Reflexive Property
Angle A is congruent to Angle BCD by Alternate Interior Angle Theorem
Angle BCD is congruent to Angle FCE by Vertical Angles Theorem
Angle A is congruent to Angle BCD by Transitive Property
The equation for speed is s=d/t, s=276/6.5. Then, you divide 276 in 6.5: s is approximately 42 miles/hour. So, he drove 12 miles/hour faster getting there than coming back home.
