I believe the second one : drawing a number from a hat, not replacing it, and then drawing a second number
- <u>To visualize 5.3</u><u>7</u><u> more accurately, divide line segment between 5.37 and 5.38 in ten equal parts. 5.3</u><u>7</u><u> lies between 5.377 and 5.378.</u>
- <u>Again </u><u>use </u><u>divide</u><u> above portion between 5.377 and 5.378 into 10 equal parts, which shows 5.3</u><u>7</u><u> is located closer to 5.3778 than to 5.3777</u><u> </u><u>so </u><u>we </u><u>can </u><u>get </u><u>the </u><u>answer</u>
<h2><u>hope</u><u> it</u><u> helps</u></h2>
Answer:
estimate units and solve.
Answer:
(x - 7)(x + 3) = 0
Step-by-step explanation:
To factorise the quadratic
Consider the factors of the constant term (- 21) which sum to give the coefficient of the x- term (- 4)
The factors are - 7 and + 3, since
- 7 × 3 = - 21 and - 7 + 3 = - 4, thus
(x - 7)(x + 3) = 0 ← in factored form
