The two triangles are similar, so will have a direct scale factor. We can find this by using the given measurements, 10÷8=1.25. So the scale factor from the smaller to the bigger triangle is 1.25. This means that 1.25×(x+6)=AE. We can solve this as we would with a regular linear equation:
1.25(x+6)=2x+6
1.25x+7.5=2x+6
1.5=0.75x
2=x
∴ AE is 2x+6=10
2 (5 - 8x) - 13 = 9 (1 - x) - 12
10 - 16x - 13 = 9 - 9x - 12
10 - 13 - 16x = 9 - 12 - 9x
- 3 - 16x = - 3 - 9x
- 3 + 3 = - 9x + 16x
0 = 7x
0/7 = x
0 = x

Answer:
First box - divide both by 2
Second box - subtract 8 by 6
last box - subtract x
Answer: -1
Step-by-step explanation: So -3/5 - 2/5, is also -3/5 + -2/5 which when you add those together 2 + 3 is 5 so -3/5 + -2/5 = -5/5 which simplifies to -1
Answer:
-1(4c+1)(c-5)
Step-by-step explanation:
First get rid of the negative by factoring out -1, then determine what factors of 5, the constant term(the number without the x), multiply by 4 to add up to -19. The only factors of 5 are 1 and 5, so we will use these. (4c+1)(c-5) can be "foiled" to check our answer.
