Answer:
20+7x
Step-by-step explanation:
you'd multiply 2 by 5 and 2 by 3x which will give you 10+ 6x; Then add the others : 2(5+3x)+(x+10) would be 10+6x+x+10 so its 20+7x. .
If it's written correctly, I believe the points are (5 , 140) and (20 , 520). First equation indicates a parabola and the second a line. The parabola crosses the line at two points.
4z>-60
divideby 4
z>-15
x+19 <=-5
subtract 19 from each side
x<= -24
Answer: 1078m^2
Step-by-step explanation:
ok, so the surface area of a figure is the area of that entire thing so what we are going to do is find the area of every part of this , the area of each base is 17*19. the area of each of the other sides are 6*17 and 6*19.
