Answer:
A -6 < x ≤ -3
Step-by-step explanation:
21 ≤ - 3(x - 4) < 30
Divide all parts by -3. Remember that flips the inequalities
21/-3 ≥ - 3/-3 (x - 4) > 30/-3
-7 ≥ (x - 4) > -10
Add 4 to all sides
-7+4 ≥ x - 4+4 > -10+4
-3 ≥ x > -6
Rearranging the order
-6 < x ≤ -3
Answer:
None
Step-by-step explanation:
Assuming you mean sides of a right triangle, we can use the Pythagorean theorem (A^2 + B^2 = C^2)
We have A and B, so we can plug those into the equation.
(16)^2 + B^2 = (14)^2
(16)^2 is 256 and (14)^2 is 196. Plug those in.
256 + B^2 = 196
Get rid of the 256 by subtracting.
B^2 = 196 - 256
B^2 = -60
√B^2 = √-60
You can't take the square root of a negative number, so the solution is not possible. We can confirm because C cannot be bigger than A or B.
Answer: The answer is 75

Answer:
2/3(x+9)=22
Step-by-step explanation:
You take the 3 squared which is 9 then, you divide that by three then you get 3
