Answer:
Step-by-step explanation:
2.
Surface area = ( 6 *10 ) *3 + ( ( 7*4.87) /2)*2 = 180 + 34.09 = 214.09
3.
Surface area = (5*10) *3 + (( 7*4.2)/2)*2 = 150 +29.4 = 179.4
Answer:
7.07 units
Step-by-step explanation:
Use the Pythagorean theorem for the right triangle:

If a = x, b = x, and c = 10, then

Answer:
You dont add the denominators since they are the same. You just add the tops. Therefore your answer is 1 or 3/3.
Step-by-step explanation:
Answer:
x =
, y = 
Step-by-step explanation:
1. Isolate for x in one of the equations:
2x = 9x - 14y
2x-9x = 9x-9x -14y
-7x = -14y
-7x/-7 = -14y/-7
x = 2y
2. Substitute 2y in for x in the second equation:
9(2y) = 40 - 14y
3. Simplify:
18y = 40 - 14y
4. Isolate for y:
18y+14y = 40 -14y+14y
32y = 40
32y/32 = 40/32
y = 
5. Substitute the new y-value into the simplified expression x = 2y:
x = 2(5/4)
x = 
hope this helps!
C' ( 4, -2 )
this is the explanation sort of
c ( -2, -3 ), since it is translated six units to the right, add 6 to the x-coordinate and since it is translated one unit up, add 1 to the y-coordinate
