Answer:
x=2
Step-by-step explanation:
assuming this shape is euclidean (don't pay attention to this just some extra info, assume that all triangles on a sheet of paper have angles summing to 180)
The sum of all angles in a triangle is 180, so
90+60+15x=180
150+15x=180
15x=30
x=2
The problem uses the concept of Combination where there are number of members chosen from a group and there order is not important. Thus, the expression that would best describe the given above is 30C6 which means the combination of 30 taken 6. The numerical value for this is 593775.
Answer:
10%
Step-by-step explanation:
We have procent:
520 —-> 100%
572 ——> x%
So, it is:
520*x=572*100
X=57200/520=110%
110%-100%=10%
X(x - 2) = 4 [upon multiplying and moving the 4 becomes x² - 2x - 4 = 0] x(2x + 3) = 12 [upon multiplying and moving the 12 becomes 2x² - 3x - 12 = 0] 3x(x + 8) = -2 [upon multiplying and moving the -2 becomes 3x² + 24x + 2 = 0]
