PLS CAN SOMEONE HELP MEEE PLS ITS URGENT

x=75 y=60

Step-by-step explanation:

isosceles have the same sides and same angles so the 75 applies to both sides and a triangles corners = 180 so 75+75= 150 subtract that from 180 and you get 30 which is the last corner of that triangle which that angle is 30+y=90 so subtract by 90 and you get 60

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
