Answer: The equation modeled is
3x2 – 4x + 1 = (3x – 1)(x – 1) . Much easier to understand with the symbols:
=
Step-by-step explanation:
x x .x -1
x x² x² x² -x
-1 -x -x- x +1
That is how I interpreted the "tile" set up.
Now count up the factors:
There are 3 x² . There are 4 -x and a +1
That's the third answer choice.
Answer:
D. 11.8 cm.
Step-by-step explanation:
This is a 30-60-90 triangle, which means that the hypotenuse is 2x, the short leg is x, and the long leg is x.
In this case, the hypotenuse is 5.
5 / 2 = 2.5. That is the short leg.
The long leg is 2.5 * = 4.330127019.
5 + 2.5 + 4.330127019 = 7.5 + 4.330127019 = 11.83012702, which is about D. 11.8 cm.
Hope this helps!
