Of Janet’s two solutions, both x=5 and x=-2 are correct because both x=-2 and x=5 are extraneous solutions
<h3>Logarithmic function</h3>
Given the log function expressed as:
log(x-3) + logx=1
According to the law of logarithm, addition becomes product to have:
log x(x -3) = log₁₀10
x² - 3x = 10
x² - 3x -10 = 0
x² - 5x + 2x - 10 = 0
x(x-5) + 2(x-5) = 0
(x+2)(x-5)=0
x = -2 and 5
Of Janet’s two solutions, both x=5 and x=-2 are correct because both x=-2 and x=5 are extraneous solutions

Given:
The function is

To find:
The range value if the domain value is 1.75.
Solution:
Domain is the set of input values and range is the set of output values.
Here, range value if the domain value is 1.75. It means the value of function f(x) at x=1.75.
Substitute x=1.75 in the given function.



Therefore, the required range value is 4.5.
Answer:
To find the sum of interior angles in a polygon, we can use the formula:
where n is the number of sides.
Since this is pentagon (5 sides), then 
The missing angle would then be

Since angles on a straight line add up to 180, then


Answer:
I think c but I'm not sure
