Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2
Answer:
0 or infinity i believe
Step-by-step explanation:
slope equation is rise over run or y2-y1 over x2 - x1, so 5 - (-1) turns into 5+1 because of the double negative so that equals six. then 3-3 is 0 so it would be 6 over zero and by dividing that'd equal zero aka infinity for slope
It can go into 100 feet 4 times. After you add four times you should have 97 and 4/8 or 97 and 1/2
Answer:
2sin(2x)-2sinx+2sqrt3cosx-sqrt3 = 0
-----
4sin(x)cos(x) - 2sin(x) + 2sqrt(3)cos(x) - sqrt(3) = 0
-----
Factor:
2sin(x)[2cos(x)-1] + sqrt(3)[2cos(x)-1] = 0
-----
[2cos(x)-1][2sin(x)+sqrt(3)] = 0
Solve:
2cos(x)-1 = 0 or 2sin(x)+sqrt(3) = 0
cos(x) = 1/2 or sin(x) = -sqrt(3)/2
x = +/-pi/3 or x = -pi/3 or (4/3)pi
hope this helps!
