Answer:

The perimeter is 27 km

The area is 21 km^2

Step-by-step explanation:

The perimeter of a triangle will just be all of the sides added up.

12 + 9 + 6 = 27 km

The area of a triangle is:

A = 1/2 * base * height

The base is 6 km, and the height is 7 km. Substituting the values in and solving, we get:

A = 1/2 * 6 * 7

A = 3 * 7

A = 21 km^2

Answer:

Option C is correct

The coordinate of C' or the transformed point of C is (-6, 5)

Step-by-step explanation:

From the given graph:

In triangle ABC:

Coordinate of C is:

C(-3, 4)

The rule of transformation is given:

$(x, y) \rightarrow (x-3, y+1)$

We have to find the coordinate of C'.

Apply the transformation on coordinate C:

$C(-3, 4) \rightarrow C'(-3-3, 4+1) = C'(-6, 5)$

Therefore, the coordinate of C' is (-6, 5)

What is (128 +7x- 12) = (4x - 3)?

podryga [215]

Answer:

x = -119/3 = -39 2/3

Step-by-step explanation:

(128 +7x- 12) = (4x - 3)

Combine like terms

(116 +7x) = (4x - 3)

Subtract 4x from each side

116 +7x-4x=4x-4x-3

116 +3x = -3

Subtract 116 from each side

116-116 +3x = -3-116

3x = -119

Divide each side by 3

3x/3 = -119/3

x = -119/3

x = -39 2/3
