Answer:
Step-by-step explanation:
I actually forgot what a trapezoid was and had to look it up.
Anyway, in an isosceles trapezoid the two legs are the same length, so we now have 3x-9=7x-10. Now it's simply a problem where you solve for x.
3x-9=7x-10
-9=4x-10
1=4x
x=1/4
Hope this helps :)
The answer is 9. When multiplying by decimals, you add up how many numbers are after the decimal in both numbers. So, the first on had 5, the second had 4.
5 + 4=9
