Answer:(k+1)(2K+7)
Step-by-step explanation:
Using the quadratic formula
X=-b±-√b^2-4ac/2a
ax^2+bx+c=0
2k^2+9k+7=0
In this case a=2,b=9,c=7
-9+-√9^2-4(2)(7)/2(2)
(-9+√25)/4=-9+5/4=-1
(-9-√25)/4=-14/4 =-7/2
X=-1,X=-7/2
So (K+1)(k+7/2)
So (k+1)(2k+7)
Answer:
Martha needs 10 more days
Step-by-step explanation:
25 Liters = 5 days
25*2=50 so double equation
25*2=5*2
50 Liters =10 days
it takes 10 days to jar 50 Liters of jam
For the midpoint, you find the differences in x values and y values then divide them by 2. Like so:
Let's do x first:
(-16-0)/2 = (-16)/2 = -8
So our x coordinate is -8.
Now Y:
(-16)/2 = -8
So our Y coordinate is -8 as well.
So your answer is:
(-8,-8)
