The way I picture this thing, it's made of three rectangles
that are joined together.
-- One rectangle is 3 x 6 meters.
-- One rectangle is 3 x 8 meters.
-- One rectangle is 3 x 10 meters.
-- Their 3-meter edges are all taped together to make a 'tube'.
-- It's 3 meters long, and it has 3 sides.
-- When you look at the ends of the tube, they're both
right triangles with sides of 6, 8, and 10 meters.
-- The area of each side = 1/2 (base x height)
= 1/2(6m x 8m) = 24 square meters.
2 ends = 48 square meters.
-- The lateral surface area is the area of the three rectangles
that make the 'tube'.
-- Area of the 6 x 3 rectangle = 18 square meters
-- Area of the 8 x 3 rectangle = 24 square meters
-- Area of the 10 x 3 rectangle = 30 square meters
-- Total lateral area = (18 + 24 + 30) = 72 square meters.
-- When you add the ends to it, you get
(72 + 48) = 120 square meters
for the total area.
Answer:
D
Step-by-step explanation:
In standard for for polynomials, the highest degrees need to be at the front, followed by the next highest, etc... all the way down to the lowest. D is the only answer option to do that.

Step-by-step explanation:
m= y2 - y1/ x2 - x1( slope of a line)
m = 8 -0 / 7- 0
8/7 = m
m = 1.1
since m =y - y1/ x - x1
1.1 = y - 0/ x-0
1.1 = y/x(cross multiply)
y = 1.1 x
y -1.1 x = 0
or
y - 8/7 x = 0
Answer:
If all the items are sold, the profit percentage is 14.28%.
Step-by-step explanation:
Given that the cost of 21 articles is equal to selling price of 18 articles, to find the profit or loss percent the following calculation must be performed:
21 = 100
21 - 18 = X
21 = 100
3 = X
(3 x 100) / 21 = X
300/21 = X
14.28 = X
Therefore, if all the items are sold, the profit percentage is 14.28%.
The answer is -23. Hope I helped
