Answer:

x = -7.22 or -7 2/9

Step-by-step explanation:

-73 = 4(3x - 2) - 3x

-73 = 12x -8 -3x

-73 = 9x - 8

-65 = 9x

-65/9 = x

-7.22 or -7 2/9 = x

Answer:

x = -65/9

Step-by-step explanation:

-73 = 4(3x - 2) - 3x

-73 = 12x - 8 - 3x

-73 = 12x - 3x - 8

-73 = 9x - 8

+8 +8

-------------------

-65 = 9x

/9 /9

-------------------

-65/9 = x

Answer:

The length of bottom side of the scaled copy is 12 u

Step-by-step explanation:

To solve this problem we have to know that to calculate the area of a triangle we use the following formula

a = area

b = base

h = height

a = b * h

In the triangle A the base and the height are equal to 3

b = h

Now that we know that b & h we can calculate the base of the scaled copy

72 u² = b * b

72 u² = (b)²

√(72 u²) = b

12 u = b

The length of bottom side of the scaled copy is 12 u

In order to make point D as the vertex in the construction as triangle ABC, the third arc should cross the second arc.

In Geometry, an arc can be defined as a trajectory that is generally formed when the distance from a given point has a fixed numerical value.

In order to make point D as the vertex in the construction as triangle ABC, you must ensure that the third arc crosses the second arc as illustrated in image attached below.
