Answer:
x=−5+√29 or x=−5−√29
Step
Let's solve your equation step-by-step.
x2+10x+10=14
Step 1: Subtract 14 from both sides.
x2+10x+10−14=14−14
x2+10x−4=0
For this equation: a=1, b=10, c=-4
1x2+10x+−4=0
Step 2: Use quadratic formula with a=1, b=10, c=-4.
x=
−b±√b2−4ac
2a
x=
−(10)±√(10)2−4(1)(−4)
2(1)
x=
−10±√116

x=−5+√29 or x=−5−√29
Answer:
984
Step-by-step explanation:
DVDs comprises 31.3% of total. And we also know that there are 308 DVD. Thus, we can say:
308 is 31.3% of total
We can let total be x, thus we can write an equation as:
308 = 0.313x
Solving for x:

We can round and say there are 984 total movies
0.7x-1.4=-3.5
Add 1.4 to both sides:
0.7x=-2.1
Divide 0.7 to both sides:
x=-3
