Answer:
311
Step-by-step explanation:
280 + 31 = 311
Divide the numerater by the denominater by the greatest commen facter
Given: 3y cos x = x² + y²
Define

Then by implicit differentiation, obtain
3y' cos(x) - 3y sin(x) = 2x + 2y y'
y' [3 cos(x) - 2y] = 2x + 3y sinx)
Answer:
Answer:
36
Step-by-step explanation:
Substitute the A for the 9, since A=9, and multiply the numbers
hmmm let's find the distance between B and C first off.

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
