Think of finding each surface area as finding the area of a 2D object
Lets start with the triangle.
area of right triangle = ab/2
6*8=48 48/2= 24
so the triangles surface area is 24, remeber there are 2 identical triangles so multiply 24 by 2 and get 48 again
now lets do one of the rectangles
area of rectangle is ab
so 4*10=40
lets add that to the total
48+40 = 88
Now lets do 8*4= 32
add to total again, 88+32= 120
and now do the last rectangle, 6*4=24
Now get the grand total of it all, 120+24 = 144
Thats how you do it :)
Answer:
b x =-2/3
Step-by-step explanation:
-3(2x+1) + 3x = 6x + 3
Distribute
-6x -3 +3x =6x+3
Combine like terms
-3x-3 = 6x+3
Add 3x to each side
-3x+3x-3 = 6x+3x+3
-3 = 9x+3
Subtract 3 from each side
-3-3 = 9x+3-3
-6 = 9x
Divide by 9
-6/9 = 9x/9
-2/3 =x
What kid of math is this?
You should try doing this
9 times 100
then divide your answer by 12.
Answer:
2
Step-by-step explanation:
rate of change = (y2-y1)/(x2-x1)
(20-26)/(5-8)
-6/-3 = 2
