<u>Answer</u>:
The discriminant of 3 x squared minus 10 x = negative 2 is 76
<u>Explanation</u>:
<u>Given</u>:
..........(1)
We can find out the discriminant by using the formula
So from the equation (1)
We have b = -10
a= 3
c= 2
Now put all these values of a,b and c in the formula of discriminant to find out the value of D
So
D=76
So the discriminant of the given quadritic equation = 76
Answer:
x= -2
Step-by-step explanation:
If the slope is zero, that means the line is horizontal.
<span>Answer:
Since segment AB and segment AE are congruent (given), the triangle ABE must be isoscles by definition of an isosceles triangle.
From that it follows that angle ABC must be congruent to angle AED, again by definition of an isosceles triangle.
Then because you are given that segment BC and segment DE are congruent, triangle ABC must be congruent to triangle AED by SAS.
Now you aren't clear whether angle 1 is angle ACB or ACD. Assume it is ACB, then ACB is congruent to ADE by CPCT. Therefore angle 1 equals angle 2. QED.
If angle 1 is ACD and angle 2 is ADC, then since angle ACB is supplementary to angle ACD, angle ADE is supplementary to angle ADC, and from the step above angle ACB is congruent to angle ADE, then angle ACD is congruent to angle ADC by transitive equality. Therefore angle 1 equals angle 2. QED.</span>
Answer: $9
Step-by-step explanation: If Wendy wants to own a total of 12 necklaces, that means Wendy wants to buy 9 more necklaces, since she already owns 3. We know that each necklace is a dollar.
So if Wendy buys 9 necklaces for a dollar each, then the total price will be $9 for Wendy to own a total of 12 necklaces.
( 9 x 1 = 9)
Add all the sides then divide by how many sides it is
