If you multiple the numbers together...you will get the answer....480 pounds of water in total
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)
(-2,7)(3,-3)
slope(m) = (-3-7) / (3 - (-2) = -10/(3 + 2) = -10/5 = -2
y = mx + b
slope(m) = -2
use either of ur points (-2,7)...x = -2 and y = 7
now sub and find b, the y int
7 = -2(-2) + b
7 = 4 + b
7 - 4 = b
3 = b
so ur equation is : y = -2x + 3 or 2x + y = 3
