Answer:multiply
Step-by-step explanation:6x4 but i aint sure tho
Since 300 is 100%, you treat it as such.
300/(100/70) = 210 (rounded)
You do a similar thing for 600
1/4 of 100 is 25
100/25 = 4
600 / 4 = 150
70% of 300 is more.
The number which could be added to both sides of the equation to complete the square is; -2.25.
<h3>Which number could be added to both sides of this quadratic equation to complete the square?</h3>
The quadratic equations give in the task content is; 1=x²-3x. Hence, to express the equation by completing the square method; we have;
1 - 2.25 = (x -3/2)² - 2.25
Hence, the number which should be added to both sides of the equation is; -2.25.
