Step-by-step explanation:
It's given in the question that the roots of the eqn. are real and equal. So , the discriminant of the eqn. should be equal to 0.
Answer:
3n² + 4n - n
3 x 7² + 4 x 7 - 7
first do the exponent because there is no parentheses
3 x 49 + 4 x 7 - 7
second do either multiplication or division with ever is closes to the left
147 + 4 x 7 - 7
147 + 28 - 7
third do either addition or subtraction which ever is closes to the left
175 -7
168
finally the answer is 168
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.
