Answer:
(-11 +/- sqrt 21) / 10
or
-0.64 , -1.56 to the nearest hundredth.
Step-by-step explanation:
9v^2 + 11v + 5 = 4v^2
5v^2 + 11v + 5 = 0
Using the quadratic formula:
v = [ - 11 +/- sqrt(11^2 - 4*5*5) ] / 2*5
= (-11 +/- sqrt 21) / 10
= -0.64 , -1.56 to the nearest hundredth.

Answer:
Pythagorean Theorum:
16ft
Step-by-step explanation:
pythagorean theorum states a^2+b^2=c^2
it only works for right triangles, c is the hypotenuse, a and b are the legs
so to find b we plug in the info we have!
7.8^2+b^2=17.8^2
next we simplify:
60.84+b^2= 316.84
subtract 60.84 from both sides to isolate the variable:
b^2=256
square root both sides
b=16
16ft is the answer
I hope this helps!
