Answer:
A∩B = {2, 23}
Step-by-step explanation:
The intersection of two sets is the list of elements common to both.
2 is found in both
12, 19 are only in set A
23 is found in both
29 is only in set A
34, 40, 45 are only in set B
The intersection of the two sets is {2, 23}.
Answer:
x = 3
Step-by-step explanation:
First set up the problem like this:
14x-17 = 8x + 1
Now we subtract 14x from each side. This leaves us with:
-17 = 6x+1
Now we need subtract 1 from each side, leaving us with:
-18 = -6x
And now we divide each side by 6x, leaving us with.
3 = x.
And if you insert three into both of the equations, it will result in 25.

Answer:7/2
Step-by-step explanation:
Answer:
16.9 m
Step-by-step explanation:
Start with a half a circle. The central angle of a semicircle is 180 deg.
Now subtract 21 deg on each side.
180 - 21 - 21 = 138
The central angle is 138 deg.
The radius is 7 m.
Now we use the formula for the length of an arc of a circle given the radius of the circle and the central angle of the arc.
