Answer:

x=17

Step-by-step explanation:

Since the triangles are congruent, the angles are equal

I≅ P

3x+4 = 72-x

Add x to each side

3x+4+x = 72-x+x

4x+4 = 72

Subtract 4 from each side

4x+4-4 = 72-4

4x= 68

Divide by 4

4x/4 = 68/4

x = 17

Which equation represents the model shown below

Alona [7]

Answer:

-4x - 3 = -8

Step-by-step explanation:

On our left, we have -x in 4 places = 4(-x) = -4x

And on the left, we also have -1 in 3 places = 3(-1) = -3

Altogether in our left, we have: -4x +(-3)

That is: -4x - 3

On our right, we have -1 in 8 places, which is 8(-1) = -8

Therefore, the equation that represents the model would be:

-4x - 3 = -8
