Answer:
The number is 8
Step-by-step explanation:
Answer:
b)-9,2
Step-by-step explanation:
x^2+7x-18=0
x^2+9x-2x-18=0
x(x+9)-2(x+9)=0
(x+9)(x-2)=0
therefore
x=-9
x=2
A^2 - b^2 = (a+b)(a-b)
answer :
t^2 - 1
n^2 - 225
Answer: x = 120

Explain why it is linear
First, we need to determine the equation that represents the scenario
Let x be the number of hours worked and y be the number of figurines at x hours.
The equation is determined as follows:

This gives:


Reorder

A linear equation is of the form

By comparison,
is equivalent to 
<em>Hence, we can conclude that the situation is linear</em>
