Answer:
x - 14 < 25
Step-by-step explanation:
You solve this by replacing the words with the number, letter or symbol they equal. So a number is x and decreased is subtraction. So far you have, x - 14. Then you look at less than and you know that the less than symbol is < so you plug that in and then you put 25 on the end.

Answer:
3sqr(x)
root: x = 0
Step-by-step explanation:
Answer:
27
Step-by-step explanation:
15x-31 = 9x+11
6x-31 = 11
6x = 42
x = 7
15x -31 + 9x + 11 + s = 180
15(7) -31 + 9(7) + 11 + s = 180
105 - 31 + 63 + 11 + s = 180
153 + s = 180
s = 27
Discriminant = b^2 - 4ac
a = 4
b = 16
c = 16
16^2 - 4(4 x 16)
256 - (4x64)
256 - 256 = 0
Therefore it only has one root
