Answer:
D 5
Step-by-step explanation:
the same scaling factor s applies to all sides when transforming from the small to the large triangle.
x×s = x + 5
(x-2)×s = x +1
=> s = (x+5)/x
=> (x-2)×(x+5)/x = x + 1
=> x² + 3x - 10 = x² + x
=> 3x - 10 = x
=> 2x = 10
=> x = 5
Answer:
0
Step-by-step explanation:
2x-6=2x+15
2x-2x=15+6
0x/0=21/0
x=0
Answer:
y = 7
Step-by-step explanation:
Add -4y and 6y
Move all terms not containing y to the right side of the equation.
Divide both sides by 2
Just imagine having 6 one blocks. Then you have 7 groups of those 6 one blocks. Then that's it!
