452,489 to the nearest thousand is 452,000

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

squares, rhombus, rectangles

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
