yes your correct
A)
Answer:
x = 12
Step-by-step explanation:
sqrt(x+4) - 3 = 1
First get the sqrt all by itself on one side of the equation. Add 3 to both sides of the equation.
sqrt(x+4) = 1 + 3
sqrt(x+4) = 4
To "fix" the sqrt, that is, "undo it" and get rid of it, you have to SQUARE both sides of the equation.
(sqrt(x+4))^2 = 4^2
x + 4 = 16
subtract 4 to finish up.
x = 12
Check:
sqrt(12 + 4) - 3 = 1
sqrt16 - 3 = 1
4 - 3 = 1
1 = 1 Check!
Assuming that the side of the triangle marked 13.5 is tangent to the circle, the there's a right angle where the radius meets the tangent segment. The triangle is then a right triangle and the Pythagorean Theorem applies.
-12 is an integer number, and you can write it as {-12}{1}
7.3 is a rational number, and you can write is as {73}{10}
0.41 is a rational number, and you can write is as {41}{100}
6 is a whole number, and you can write it as {6}{1}
3 1/2 is a rational number, and you can write is as
3+{1}{2}={6}{2}+{1}{2}={7}{2}
Hopes this helps also will you mind giving me brainliest?
