In a square all 4 sides are equal, so when you cut it along the diagonal to make a triangle, both the base and the height of the triangle would be the same.

The area of a triangle is found by the formula 1/2 x base x height

Since the base and height are the same the formula becomes Area = 1/2 x S^2 ( where S is the length of a side).

The area is given as 0.72 square units.

Now you have 0.72 = 1/2 x S^2

First multiply both sides by 2:

1.44 = S^2

To find S, take the square root of both sides:

S = √1.44

S = 1.2

The side length is 1.2 units.

write an expression that represents the cost of one carful of nonstudents ($12 per person). Use x as the number of people who ri

gayaneshka [121]

Okay so each person is $12

Then you need to times that for how many people are in the car x.

Since x is a variable and not a number it can go right next to the 12

You answer should be 12x
