Answer:
372 in ^2
Step-by-step explanation:
Wrapping a present is surface area
SA = 2( lw+wh+hl)
= 2 ( 12*3 + 12*10 + 3*10)
= 2 ( 36+120+30)
= 2 (186)
= 372 in ^2
Answer:
M = (13, - 6 )
Step-by-step explanation:
The coordinates of the midpoint are the average of the x and y coordinates of the endpoints.
L (- 9, 4 ) , let M = (x, y ) , then
= 2 ( multiply both sides by 2 )
- 9 + x = 4 ( add 9 to both sides )
x = 13
and
= - 1 ( multiply both sides by 2 )
4 + y = - 2 ( subtract 4 from both sides )
y = - 6
Then
coordinates of M = (13, - 6 )
