Answer:
x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11
Step-by-step explanation:
This polynomial is a quadratic. Its coefficients are a = 1, b = 1 and c = 3.
Thus, the discriminant b^2-4ac is 1^2 - 4(1)(3), or 1 - 12, or -11.
Because the discriminant is negative, the roots are complex.
The roots are:
-1 ±√(-11) -1 ±i√11
x = --------------- = ----------------, so x = -1/2 + (i/2)√11 and x = -1/2 - (i/2)√11
2 2
The area of the square would be 4 units squared. 2 multiplied by 2 is 4, and the units are squared because we are finding area.
So you would use:
[ ((V2<span> - V</span>1) / |V1<span>|) * 100 ]
</span>V1<span> = 87.5 to V</span>2<span> = 125
</span>
<span><span>= ((125 - 87.5) / |87.5|) * 100
= (37.5 / 87.5) * 100
= 0.428571 * 100
= 42.8571% change
= 42.8571% increase

<u>Step-by-step explanation:</u>
According to question, Lynn works as a part-time vendor selling necklaces for $15 each and bangles for $10 each. She needs to earn a minimum of $300 per week to cover her expenses. The inequality for above scenario will be :
where, x is number of necklaces & y is number of bangles.
A.
Lynn will meet her goal if she sells 12 bangles and 12 necklaces. i.e. x=12 and y=12 , putting values inequality : which follows inequality . True statement!
B.
Lynn will meet her goal if she sells 20 bangles and 6 necklaces.
putting values inequality : which follows inequality . True statement!
C.
Lynn will meet her goal if she sells 6 bangles and 12 necklaces. putting values inequality : , which follows inequality . True statement!
D.
Lynn will meet her goal if she sells 2 bangles and 18 necklaces.putting values inequality : , which follows inequality . True statement!
