what is the area of a triangle which has a base of 15cm and a perpendicular hight of 12 cm
The point of contact of the tangent line x-2y+12 = 0 with the circle x^2+y^2-x-31 = 0 is at (-2, 5)
45/30
expand and fully simplify x(y+2)-y(x-2)
(-2x÷3)-4=8
5x+35
solve the follo
2x*2+ y*2 = 19 ……1
X + 3y = 0 …………2
8-(-7)
(-2y÷4)+8=6
if y-1/y=6, find the value of y^2+1/y^2 and (y+1/y)^2
