Answer:
slope = 4/1 or 4
Step-by-step explanation:
I think it is 210
because 15x14=210
If the points P, Q and R are collinear, then a slope of line PQ and a slope of line QR are equal.
The formula of a slope:

PQ → (0, 3), (2, 0).
Substitute:

QR → (2, 0), (4, -3).
Substitute:

CORRECT :)
<h3>Answer: m = -1.5.</h3>
Answer:
87
Step-by-step explanation:
earning rate (R) = $5/hr
total (T) = $287
time (t) = 40 hr
tips = T - Rt
= $287 - $5*40
$87
The surface area is the sum of the area of the six sides...
A=2(xy+xz+yz)
A=2(8*3+8*5+3*5)
A=2(24+40+15)
A=2(79)
A=158 cm^2
