Mr. sanchez is building a room that is 20 feet long and 15 feet wide. construct a scale drawing of the shed. use a scale 1/2 inch = 5 feet.

This is my question~~ ( r ^ 4 - 2r ^ 3 - 23 r ^ 2 - 4r - 32)÷(r+4) ~~ i must use long division to solve it : / i was wondering if anyone world like to solve it. and if so, share step-by-step explanations! you! ❤

Use the elimination method to solve the systems of equations.choose the correct ordered pair. 7x+4y=39

Write an equation of the line that passes through the point (2, 3) and is perpendicular to the line x = -1. a) y = 1 b) y = 3 c) y = 0 eliminate d) y = -3
