-2n + 1.8 = 3.2
Subtract 1.8 from both sides
-2n = 1.4
Divide both sides by -2
n = 1.4/-2 = 0.7/-1 = -0.7
n = -0.7
Check your work:
-2(-0.7) + 1.8 = 3.2
1.4 + 1.8 = 3.2
3.2 = 3.2
The answer is B. -0.7
Answer:
The correct answer would be 40
Step-by-step explanation:
To find two square roots being multiplied together, you can multiply the numbers beneath the symbol.
√2 x √800 = √1600
Now you can perform the square root operation.
√1600 = 40
30 60 90 triangle
ratio of short leg : hypo = x : 2x
given short leg x = 4 ft
so hypo a = 2x = 2 * 4 = 8
answer
a = 8 ft
----------------------------------------------
P.S.
if you need to do by using cos sin tan then
Cos (60) = Adj/Hypo = 4/a
a = 4/cos(60) as you know cos(60) = 1/2
so
a = 4 /(1/2 = 4 * 2/1 = 8
answer: a = 8 ft
A. m = 0 || This is incorrect, because m being equal to 0 is a solution in and of itself.
B. m = m || This is incorrect, because m being equal to itself means that there are an infinite number of solutions.
C. 2m + 1 = m - 2 | m = -3 || This is incorrect, because m can be solved for and has a solution.
D. m + 4 = m - 4 | 4 = -4 || This is correct because 4 is not equal to -4, and thus there is no solution.
Hope this helps!! :)
