Answer:
option a
Step-by-step explanation:
7/8 * -4/21
=7*-4/8*21
=-28/168
=-1/6
In maths product means multiplication.
Answer: 10 1/2, which can be simplified as 10.5
Explanation: First, set up a proportion with acres of corn to time in hours:
8 3/4 acres = x acres
5/6 hour = 1 hour
Reorder the terms:
x = (8 3/4) / (5/6)
To figure that out the math, change the mixed fraction to an improper fraction, and change the division into a multiplication:
x = (35/4) * (6/5)
Next cancel out:
x = (7/2) * (3/1)
x = 21/2
Lower that faction the the lowest denominator:
21/2 = 10½
Thus, your answer is 10½, or in other words 10.5
Hope this helps! :)

Step-by-step explanation:
<u>Q1</u>
- y = (x + 3i)(x - 7)
- y = x² + 3ix - 7x - 21
- <u>y = x² + (3i - 7)x - 21</u>
<u>Q2</u>
- y = (x - √5)(x - i)
- y = x² - √5x - ix + √5i
- <u>y = x² - (√5 + i)x + √5i</u>
