Answer:
Step-by-step explanation:
n^2 - 3n - 418 = 0
(n-22)(n+19) = 0, positive real number is 22
The value of x in the equation is 23.
<h3>How to solve equation?</h3>
46 / x = 2
The equation above have one solution because the value of x is a single value.
46 / x = 2
cross multiply
2x = 46
divide both sides by 2
2x / 2 = 46 / 2
x = 23
A value of x that makes an equation true is 23, which when substituted into the equation and simplified makes the equation turn into x = 23.
A value of x that makes an equation false is 46, which when substituted into the equation and simplified makes the equation turn into x = 46.

Answer:
27 inches
Step-by-step explanation:
To find the length of the diagonal, we just need to use the cosine relation of the 48° angle.
The adjacent side to the angle is the height of the canvas, and the hypotenuse formed is the diagonal of the canvas. So, we have that:
cos(48) = height / diagonal
0.6691 = 18 / diagonal
diagonal = 18 / 0.6691 = 26.9 inches
Rounding to the nearest inch, the diagonal of the canvas measures 27 inches
Answer:
the 12th term of the arithmetic sequence would be 13a - 12b
Step-by-step explanation:
as you can see from the sequence, it goes up by 1. 2a - b became 3a -2b as an example.
A: -20b∧9
B: -3rx²y²+12x³y
C: -21m∧6+7m∧5+35m∧4
