These are your coordinates, because you just kove the polygon down by 2 then get it moves to the left <
150/4 = 37.5cm. You divide by four because there are four sides on a rectangle. But 37.5 is the cm of a square. Since it says one of the sides is 15cm greater, you subtract 37.5 - 15 = 27.5cm on 2 of the width. While the other 2 lengths are greater than the width by 15 cm, so you add 15 to 37.5 which gives you 52.5cm. So the 2 width are 27.5cm and the length is 52.5cm.
Answer:
2x⁴ - 11x³ + 7x² + 5x - 3
Step-by-step explanation:
(2x²-3x+1) * (x²-4x-3) = 2x⁴ - 8x³ - 6x² - 3x³ + 12x² + 9x + x² - 4x -3
= 2x⁴ - 11x³ + 7x² + 5x - 3
B is the right answer i think
Answer:
12
Step-by-step explanation:
If there are 3 classrooms that each have 25 desks and there are a total of 87 students, how many more desks need to be added to a 4th classroom, that was originally empty, so that each of the students has a desk to sit in?
25 * 3 = 75
87 - 75 = 12
