👉🏼Make x the subject of 9x+4y = 2(z+3x)

👈🏼Calculate x in the diagram below:

👆🏼Expand and simplify (x+2)(2x-1)²

👇🏼The point A has coordinates (-6,0), the point B has coordinates (0,3) and the point C has coordinates (9,-1). Find the equation of the line that passes through C and is perpendicular to AB.

🖐🏼If f(x) = 3x+2 and g(x) = (x-3)², then what is fg(x)?
