Answer:
x = 10
Step-by-step explanation:
Since the triangles are similar the ratios of corresponding sides are equal
= 
, that is
= ( cross- multiply )
20(4x + 2) = 84x
80x + 40 = 84x ( subtract 80x from both sides )
40 = 4x ( divide both sides by 4 )
x = 10
1. set up the equation which makes these shapes equal, 1/2(2(x+1)) = 1x
2. solve, x+1=x, 1=0
3. since this is impossible, there is no solution and zero answers
Answer: c. f - 3 + 6d
Explanation: 5d - d + 4 + 2d - 5f - 6f - 7
- 5f - 6f = f
4 - 7 = -3
5d - d = 4d, 4d + 2d = 6d
Is there any choices if not it could be 1 - 2 or abouve the first nuber x has to be smaller and y has to be bigger
