A scientist mixes x liters of water into a container that has 10 liters of a mixture that is 12% salt and 88% water. The function f(x) = 1.2 / (x+10) represents the percent of the sat in the new mixture. How many liters of water must be added to make 1% salt mixture

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36

step-by-step explanation:

i believe a. 12x≥120 is the answer

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
