Find x and QR if APQR is an isosceles triangle with PQ β QR.
P.
x+1
2x + 1
R
3x - 8
A x = 9, QR = 10
B
x = 1.5, QR = 5.5
= 9. QR = 19
Help me Please
Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. β n(n β 1)cnxn β 2 n = 2 β 4 β ncnxn n = 1 + β cnxn n = 0
Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = β3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, β6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (β5, 1) is y = 1.
