Answer:
X=23
Step-by-step explanation:
You should know that a triangle =180 degrees
Add all your angles together and =180
66+2x+3+3x-4=180
add similar terms
5x+65=180
Move your 65 to the other side
5x=115
x=23
(Optional)
to check if your answer is right substitute your x and add all angles together you should get 180 degrees.
The value of the function f(x)=6/-2+2
at x=4 after rounded to the nearest tenth is -2.4.
Given Function of x : f(x)=6/-2+2
The given function showing the relationship between x and f(x) is f(x)=6/-2+2
where e is exponential and we have to find the value of f(4) by just putting the value of x=4 in the given function and round to the nearest tenth means replacing a number with an approximate value.
f(4)=6/-2+2
( The value of e is 2.7812)
f(4)=-3+2
f(4)=-3+2*0.30119 (The value of
is 0.30119)
f(4)=-3+0.60238
f(4)=-2.3972
Round -2.3972 to tenth is -2.4.
Hence the value of function of at x=4 is -2.4.

Answer:
76
Step-by-step explanation:
The first thing that you want to do is get rid of the parenthesis by multiplying 3 by 2 so the equation is 2 times 32 + 6 times 2. next you want to mutiply 2 and 32 to get 64 then multply 6 by 2 for 12 then add 12 and 64 together
