Drag the tiles to the correct boxes to complete the pairs. Use this table to match the molecules with their estimated masses. Atom Mass (in grams) hydrogen 1.67 × 10-24 oxygen 2.66 × 10-23 carbon 1.99 × 10-23 nitrogen 2.32 × 10-23 H2 (2 atoms of hydrogen) CO2 (1 atom of carbon and 2 atoms of oxygen) NO2 (1 atom of nitrogen and 2 atoms of oxygen) NH3 (1 atom of nitrogen and 3 atoms of hydrogen)

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !

well what did you do it matters what you did : )

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb
