Find the standard form of the equation of the parabola with a focus at (-4, 0) and a directrix at x = 4.
Common difference of the arithmetic sequence, is


You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
ok I got this
So we need to find the value of X so
First, we need to see which one can add up to 22
as we already know, 14+8=22
so B.8
also so yk I'm not just playing I'll even put it in a calculator and show ya
Answer:
36
Step-by-step explanation: if they do 12 acres per day.. it would be 36 for three days. 12x3=36
