Answer:
-44ax^2-198x^2+66a+297
Step-by-step explanation:
there
3(1)^2-3= 0
Plug in the numbers because x=1 plug In 3(1)^2 and it equals 3 then subtract y which is 3-3= 0
1 : 100,000
Because there are 100cm in a m and 1000m in a km
100 x 1000 = 100,000
Answer:
4x+2=14
Step-by-step explanation:
Supplementary angles add up to 180 degrees more than the other, you can formulate an equation 180=(100+x)+x80=2x so, x=40 the other angle is 100 degrees more. So, the angle lengths are 40 and 140 degrees.
