A. 7/3
HOPE IT HELLS U!!!!
Answer: Yes, the scale factor is 10 :)
Step-by-step explanation:
Answer: #20, x = 3
#21, x = 1/2
Step-by-step explanation:
#20) x + 4 + x + 2+ x + 5 = x + 3 +x+3+x+1+x+1
3x + 11 = 4x + 8
<u>-3x -3x</u>
11= x + 8
<u> - 8 - 8</u>
3 = x
#21) 12x(5) = 6x + 9 + x + 10 + x + 7
60x =8x + 26
<u> -8x -8x</u>
52x = 26
divide both sides by 52
x = 1/2
Answer: The first one
Explanation: Is that right don't just rely on me haha if I helped u tell me please
I think you can draw two of them.
As you walk around the triangle in the clockwise direction,
you can run into the sides in the order of
3 ==> 4 ==> 1
or in the order of
3 ==> 1 ==> 4 .
Those are mirror images of each other. So they're not congruent,
and I think they're considered different triangles.
