Answer:
-4 <u>+</u> 2*sqrt(5)
Step-by-step explanation:
2x^2+16x-8=0
Factor out the 2: 2(x^2+8x)-8=0
Add (b/2)^2 = (8/2)^2 = 16
2(x^2+8x+16)-8 = 0 + 2*16
2(x+4)^2=40
(x+4)^2=20
x+4=<u>+</u>sqrt(20)
x=-4<u>+</u>sqrt(20) = -4 <u>+</u> 2*sqrt(5)
Answer:
The answer is : 8160 m
Step-by-step explanation:
100% correct
It is: 27/8 = 3 with a remainder of 3
D cause if u graph it each point it moved up but on the x axis it stays the same which makes it narrower
