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

Answer:
the length of the second rectangle is 33.75 in
Step-by-step explanation:
The computation of the length of the second rectangle is as follows
Let us assume the length of the second triangle be x
Now
The equation would be
4 ÷ 15 = 9 ÷ x
Now do the cross multiplication
4x = 15 × 9
4x = 135
x = 33.75 in
Hence, the length of the second rectangle is 33.75 in
0.3 X 10 to the power of 5!
the factors and prime factorization of 14 and 28. (The biggest common factor number is the GCF number) So the greatest common factor 14 and 28 is 14.Jul
