Answer:

x=144

Step-by-step explanation:

x/3-x/4=12

the common denominator must be 12,

4x/12-3x/12=12

since 4x-3x=x,

you have x/12=12,

x=12*12

x=144

Ahhh okay help me pls!
inna [77]

Answer:

The answer is Dilation of a scale factor of 4 followed by a reflection of the y axis.

Step-by-step explanation:

On the smaller triangle, the line EF has a length of 1 unit.

On the larger triangle, the line EF has a length of 4 units.

Therefore, the smaller triangle was dilated by 4, since 4x1 is 4.

The triangles was flipped over the y axis.

This means that it was reflected over the y axis.
