Answer:
x = 9.6 in
Step-by-step explanation:
The scale factor is 8:10 (difference in length.) This is simplified down to 4:5.
Method 1 (easier):
4/5 × 12 = 9.6 in.
Method 2 (harder but more comprehensive):
<em>cross-multiply</em>
<em></em>
Use the binomial expansion theorem to find and simplify each term.
y 8+8 y7+28y6+56y5+70y4+56y3+28y2+8y+1
