Answer:
x = 10
Step-by-step explanation:
We can use the Angle Bisector of a triangle and proportions to solve this problem. Put the smaller triangle over the larger triangle.
AB x+4
------ = ----------
AC 2x+1
8 x+4
------ = ----------
12 2x+1
Using cross products
8(2x+1) = 12(x+4)
Distribute
16x+8 = 12x+48
Subtract 12x from each side
16x-12x +8 = 12x-12x+48
4x +8 = 48
Subtract 8 from each side
4x+8-8 = 48-8
4x = 40
Divide by 4
4x/4 =40/4
x = 10
Answer:
D. 58
Step-by-step explanation:
The multiplication and division are performed first.
... 32 +6·5 -7 +12/4
... = 32 +30 -7 +3
Then, the Order of Operations tells you to do the addition/subtraction left to right. Of course, if you keep the sign with the number, you can do the addition in any convenient order.
... = 62 -7 +3
... = 55 +3
... = 58
Step-by-step explanation:
Use calculator:
sin x = 0.4 --> arc
x=23∘58
Trig unit circle gives another arc x that has the same sin value:
x=180−23.58
=156∘42

Hi there.
4(2 + 3i) - 2(6 - 8i); apply the distributive property.
8 + 12i - 12 - 16i; combine like-terms.
-4 - 4i is your final expression.
I hope this helps!
Put other y in the other equation
so u got: 4x-2=-3+5
4x-2=2
4x =4
x =1
Now put x in the equation
so u do like this: y=4(1)-2
y=2
solution is (1,2) good luck
