I think the answer is -44n+2
Answer:
Step-by-step explanation:
x^2/100 + y^2/25=1 -----(1)
Since 25<100
Hence the above equation is of the form x^2/a^2+ y^2/b^2=1-------(2)
Comparing (1) and (2)
a^2=100
a=10
Major axis=2a=20
P=-25/4
You can divide 25/4 and you will get 6.25 or 6 (1/4)
Ah, scientific notation. 5.6x10^-7 is another way of writing 0.00000056. What I did there was move the decimal place 7 units to the left. 7 because 10 is to the power of 7 and to the left because the 7 is negative.
8x+4+10x-6+y=180
18x-2+y=180
y=182-18x
y=degree measure of third angle.
