Step-by-step explanation:
x+90+4x-75=180
add all the sides together and since its a triangle they equal to 180
D.8
A and C are out because they would get you ether lower or equal to 20, which is equal to AC and your trying to find X in AB which is so posed to be the what equals AC+BC.
AB=AC+BC
5x=20+BC
5(8)=20+BC
40=20+BC
40=20+20
AC equals 20. AB will have to equal AC+ CB. If you put in A.4 in AB 5X you will get twenty and that not what you want. You want to get a number that will get you the an answer greater to AC. So 5(8)=40.
The answer is -225.
9 times -25 is -225.
9*-25=-225
Write it as a mixed fraction 7/5 = 1 2/5
