Expressions are mathematical statements without the equation sign
The possible integer values of q, r, and z are 3, -4 and -1
<h3>How to determine the values of the integers</h3>
The expressions are given as:
x^2 + zx - 12
(x + q)(x + r)
Both expressions are equal.
So, we have:

Expand

By comparison, we have:


Assume that q = 3.
So, we have:

Divide by 3

Recall that:

So, we have:


Hence, the possible integer values of q, r, and z are 3, -4 and -1

Answer:
d
Step-by-step explanation:
Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
so I don't know but just use the internet
