Answer:

2400 units^2

Step-by-step explanation:

If the side length is 20 units, then the area of each side is (20 units)^2, or 400 units. A cube has 6 sides.

Thus, the surface area of the cube in square units is 6(400 units^2) =

2400 units^2

Answer:

first of all the formula

y = mx+c

where m is slope and c is y-intercept.

now substitute the values-

y = 2x - 5

(for the slope here is 2 and the part where the line intercepts y axis is -5

therefore

y = 2x-5

A thin tube stretched across a street counts the number of pairs of wheels that pass over it. A vehicle classified as type A wit

aliina [53]

Answer: All possible solutions would be

(1,41), (8,33), (15,25), (22,17), (29,9), (36,1)

Step-by-step explanation:

Let the number of vehicle of type A be 'x'.

Let the number of vehicle of type B be 'y'.

Since we have given that

Number of axles of type A = 2

Number of axles of type B = 9

After 2 hours, number of counts = 101

so, our equation becomes,

$2x+9y=101$

So, all possible solutions would be

(1,41), (8,33), (15,25), (22,17), (29,9), (36,1)
