Answer:
k = -1
Step-by-step explanation:
You're given (x+4) as one of the factor for the equation
x² + kx - 20 = 0
what number does 4 multiply with to get -20? It's -5.
So
= (x+4)(x-5)
= x² + -1x - 20
= x² + kx - 20
Solution:
The grocery store is 1/6 miles far from her house.
Explanation:
We have been given that Sylvia walked 3/4 mi east from her house to the bank. Hence, the distance between the house and the bank is 3/4 miles.
Now, she walked 1/3 mi west to a gift shop. It means that she moved 1/3 miles towards her house.
Also, from the gift shop, she walked 1/4 mi west to a grocery store. It means she moved 1/3 miles plus 1/4 miles towards her house.
Hence, the distance between the grocery store and the house is
1346.275 ft is the answer
