24 miles is 1 gallon so 360 miles is 15 gallons + 24 is 384 miles so they are not equivalent!
15. x ≤ -24
x + 19 ≤ -5
x ≤ -24
16. z > -12
3z > -36
z > -12
17. 185 + c > 410; c > 225
18. C.
x - 6 ≥ 1
x ≥ 7
You multiply the area of the triangle by 2
C. $112.50
y=0.25x+50
x = 250 miles
0.25*250=62.50
62.50+50= $112.50
Answer:
-8p^4+12p^3+4p^4-8p^2+3p^2
=-8p^4+4p^4+12p^3-8p^2+3p^2
=-4p^4+12p^3-5p^2
=p^2(-4p^2+12p-5)
note: If you have to solve for X
there are steps according to formula
