5 times 2x + 5 times 10
10x+50
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.

Answer:
You will get x = 7
Step-by-step explanation:
2(3x + 1) = 9x - 19
6x+2 = 9x - 19
-6x. -6x
2 = 3x-19
+19 +19
21 = 3x
÷3. ÷3
x = 7
