12.5 is the answer this is actually really easy I miss Beginning Algebra
No you can’t add them, but you can do this: 7x+7 =0
-7 -7
7=7x
/7 /7
1=x
The since ratio is formed by the side opposite the acute angle over the hypotenuse.
Answer:
True
Step-by-step explanation:
For any function of the form 
the coefficient a produces a reflection of the function whenever 
.
We can verify it in the following way.
Take, for example, the function:
Now let's make 
Now let's in the following function:
We have:
We can see then that the function was reflected in the axis -y by placing a negative coefficient a.
You can see more examples in the attached images
Therefore we can conclude that the statement is true.
Answer:
Angle A = 30.8
Angle B = 33.2
Step-by-step explanation:
180 - 116 = 64
This means that the other two angles need to add up to 64.
I just plugged in numbers until it worked.
I got that x = 14.6
2x + 4
2(14.6) + 4
29.2 + 4
33.2
3x - 13
3(14.6) - 13
43.8 - 13
30.8
Those are your angles. To make sure they are correct you just need to add up all the angles and make sure that they equal to 180.
116 + 33.2 + 30.8 =
180
