I think you need to post a graphic.
Answer: Yes they are not equal
Step-by-step explanation: The first equation 6x=-5 comes out to x=-5/6 The second equation -1=6x+4 comes out to x=-5/6
6x-20
because you do....2 times 3x.....wich equals 6x......
next you take 2 times 10 wich equals.....20......
so it is 6x-20
Answer:
I've done alot of calculations on this but I cant get a definite answer I hope you got it I'm sorry I couldn't help you I tried but only got into a dead end
Answer: 207
Step-by-step explanation:
To find the surface area, find the area of all the shapes in the three-dimensional figure and then add them.
Find the area of the two triangles first:
1/2*b*h = area of a triangle
1/2* 8* 9= 36
36 is the area of one of the triangles.
Multiply 36 by two because there are two triangles.
=72
Then find the area of the squares/rectangles.
8*5= 40
9*5= 45
10*5 = 50
72+40+45+50
=207
