The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?

x(x − 5) = 77

x(x + 5) = 77

x − (x + 5) = 77

x + (x + 5) = 77

Simplify (x + 2)(x2 − 4x − 9).

x3 − 2x2 − 17x − 18

x3 − 6x2 − x − 18

x3 − 4x2 − 3x − 18

x3 − 10x2 − 9x − 18

step-by-step explanation:

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
