Answer:
To find - sum of the given two terms.
<h2>—————————————————</h2>
<h3>
Here ,</h3>
we basically added the like terms together..
like, the terms ( 3x and -4x ) will be added together.. and the terms ( 4 and 5 ) will be added together...
since there's none other term having "x²" as the coefficient.. so 2x² will be left as it is!
hope helpful~

Answer:
0.0050
Step-by-step explanation:
a. The events are mutually exclusive, so
b. For the same reason,
Another way to see this is to use the result from part (a), and the inclusion/exclusion principle:
and the right side reduces to 0.
c. Same as (b),
d. Same as (b),
We can also use the distributivity rule for unions and intersections to write
e. If the is the complement of , then by DeMorgan's law,
The sum of the angles, a, b and c is; 360° because, the sum measures 3 of all the equal angles in the regular hexagon.
<h3>What is the sum of all three angle Measures?</h3>
It follows from the task content that the angle measures given in the task are a, b and c which are in a cyclic polygon (hexagon) in which case, the sum of all 6 angles in the hexagon is; 720.
Consequently, the sum of angle measures; a,b and c is; 720/2 = 360°.

3x - 4y = 12 ----- (1)
x + 4y = 20 ------ (2)
equation (2) x 3:
3x + 12y = 60 ---(2a)
(2a) - (1):
12y - (-4y) = 60 - 12
12y + 4y = 48
16y = 48
y = 3 ---- sub into equation (2)
x + 4(3) = 20
x + 12 = 20
x = 8
Ans: x = 8 and y = 3 (True)
