Which of the following describes the algebraic expression 5(x+2)-3

How can we find the measure of an exterior angle if we know the measurement of an interior angle

Find the equation of a line that is perpendicular to line g that contains (p, q). coordinate plane with line g that passes through the points negative 3 comma 6 and 0 comma 5 3x − y = 3p − q 3x + y = q − 3p x − y = p − q x + y = q − p

Can someone tell me if this is perpendicular? !
