Answer:

B.  x  = -5 +/- √30.

Step-by-step explanation:

2x^2 + 20x = 10

2(x^2 + 10x) = 10

2[ (x + 5)^2 - 25 ] =10

2(x + 5)^2 - 50 = 10

2(x + 5)^2 = 60

(x + 5)^2 = 30

x + 5 =  +/- √30

x  = -5 +/- √30.

I need help with this ASAP! I will give 25 pts.

Answer:

hope this helps!

Step-by-step explanation:

From y(t) = −16t^2 − 3t + 300 find at what time the fertilizer hits the ground (has height 0)

0 = −16t^2 − 3t + 300

Using the quadratic formula (minus b plus or minus the square root of b squared minus 2 a c over 2 a) you get

t = 4.237 seconds

So the horizontal distance is 85t = 85 * 4.237 = 360.145 feet
