The picture in the attached figure
we know that
RX+RA+XA=24
XA=24-RA-RX------> XA=24-11-4----> XA=9
XA=XP+PA
so
XP+PA=9------> XP=9-PA-----> equation 1
RX/XP=RA/PA
11*XP=4*PA-----> equation 2
substitute equation 1 in equation 2
11*[9-PA]=4*PA-----> 99-11*PA=4*PA----> 15*PA=99----> PA=99/15
PA=6.6
XP=9-PA-----> XP=9-6.6----> XP=2.4
the answer is the option<span>
B. XP = 2.4, PA = 6.6 </span>
<span>The slope of a line is defined as the rate of change on the vertical axis, divided by the rate of change on the horizontal axis, Δy/Δx. So for a horizontal line, the rate of change on the y axis is zero, this means that it's slope will be 0/Δx and for vertical line, x-axis does not change, which make the denominator 0 Δy/0.</span>
Multiply w with every term in the second parenthesis:
w³-2w²t+4wt²
multiple 2t with every term in the second parenthesis:
2w²t-4wt²+8t³
add up the products: w³+8t³
