Answer:
a. x=65 because of vertical angle theorem,c. 44, b.y= 71 because of triangle angle sum theorem
Step-by-step explanation:
c. corresponding angle theorem and supplementary angle theorem so z+65+71=180 meaning z= 44
Step-by-step explanation:
2×2 + 8x + 26 =0
4 + 8x + 26 =0
4 + 26 = 0-8x
30 = 8x
divide both sides by th coefficient of x
30

=<em>3.75</em>
Answer:
B
Step-by-step explanation:
We have perpendicular bisector through a chord of the circle. We know the length, so either side of the chord is 11 due to the bisector cutting it directly in half. Since the radius is a fixed distance from the center to any point on the edge of the circle, we can draw the radius x from the circle to the end of the chord to form a right triangle.
We can use Pythagorean Theorem
to find the missing side length x. a=6, b=11 and c=x.


solution:
= $15 for 3 packages
= 5 packages per dollar (15/3)
We write the polynomial in its factored form first.
We have then:
(x + 2) * (x + 1) * (x-4) * (x-5)
We now rewrite the polynomial:
(x ^ 2 + x + 2x + 1) * (x ^ 2-5x-4x + 20)
(x ^ 2 + 3x + 1) * (x ^ 2-9x + 20)
x ^ 4 - 9x ^ 3 + 20x ^ 2 + 3x ^ 3 - 27x ^ 2 + 60x + x ^ 2 - 9x + 20
We now add terms of the same degree:
x ^ 4 + (-9 + 3) x ^ 3 + (20-27 + 1) x ^ 2 + (60-9) x + (20)
x ^ 4 + (-6) x ^ 3 + (-6) x ^ 2 + (21) x + (20)
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
Answer:
The polynomial sought is:
x ^ 4 - 6x ^ 3 - 6x ^ 2 + 21x + 20
