42 1/2 (D)
85/2=42 1/2
you divide 85 by 2 because there are two halves in one whole
Use the distributive property to multiply 7(c+4)
then answer is 7c+28
The value of the equation will be -2036.
<h3>How to calculate the equation?</h3>
It should be noted that the equation given is illustrated as:
p²m - (np + r)
m = -32
n = 2
p = -8
r = 4
In this case, we'll put the values back info the equation. This will be:
p²m - (np + r)
(-8)² × -32 - (2×-8 + 4)
-2048 - (-12)
= -2036
Therefore, the value of the equation will be -2036.

Answer:
Space between 80 evenly spaced chairs = 21m
Step-by-step explanation:
So, according to the given statement, we have the following expression:
No. of chairs ∝ 
70 chairs are 24m apart, so it can be written as:
70 ∝ 
For, 1 chair , we divide both sides by 70
∝ 
1 ∝
-----------------------(Equation 1)
<u>For 80 chairs:</u>
Multiply both sides of <em>Equation.1</em> by 80
80 ∝
80 ∝
So according to the above relation,
<em>80 evenly spaced chairs will have a space of </em><em>21 m</em><em> between them.</em>
