Answer: 220 cm squared
Step-by-step explanation: Formula for surface area of a prism...
S = 2(lw + lh + wh) l = 5 w = 10 h = 4
so
lw is 5 x 10 = 50
lh is 5 x 4 = 20
wh is 10 x 4 = 40
plug these into equation...
S = 2(50 + 20 + 40)
S = 2(110)
S = 220
-16 because a negative times a positive is a negative
Answer:
44x +56y = 95
Step-by-step explanation:
To write the equation of the perpendicular bisector, we need to know the midpoint and we need to know the differences of the coordinates.
The midpoint is the average of the coordinate values:
((-2.5, -2) +(3, 5))/2 = (0.5, 3)/2 = (0.25, 1.5) = (h, k)
The differences of the coordinates are ...
(3, 5) -(-2.5, -2) = (3 -(-2.5), 5 -(-2)) = (5.5, 7) = (Δx, Δy)
Then the perpendicular bisector equation can be written ...
Δx(x -h) +Δy(y -k) = 0
5.5(x -0.25) +7(y -1.5) = 0
5.5x -1.375 +7y -10.5 = 0
Multiplying by 8 and subtracting the constant, we get ...
44x +56y = 95 . . . . equation of the perpendicular bisector
