Answer: -7b² + 2b - 8
Step-by-step explanation:
<u>Given expression</u>
3 - b (7b + 2) + 3b - (11 - b)
<u>Expand parentheses and apply the distributive property if necessary</u>
=3 - b · 7b - b · 2 + 3b - 11 + b
=3 - 7b² - 2b + 3b - 11 + b
<u>Combine like terms</u>
=-7b² + (3b - 2b + b) + (3 - 11)
=

Answer:
657 pounds
Step-by-step explanation:
Given
Represent the amount of fertilizer with x and the yield with y.
So, we have:
Required:
Determine the yield (y) when fertilizer (x) is 73ft^3
Using linear interpolation, we have:
Substitute the x and y values using
and
;
We have:
Open bracket
To solve for y when x = 73.
We simply substitute 73 for x
<em>Hence, the yield for 73 cubic feet is 657 pounds</em>
