Answer:
I think A
Step-by-step explanation:
the measure is 140, I basically summed all of the angles of a polygon of “n”, which is 7, then I did 7-2 times 180 (900) so I can finally add up all of your measurements
If you convert the number on a percent,
then multiply the number by 100 with sign %
1.04 = 1.04 × 100% = <u>104%</u>
First, multiply. 7x-14-4x+9. Now, add the like terms. 3x-5.
