50
Step-by-step explanation:
Since AE is the bisector of angle BAC,so angle BAE and Angle CAE is equal. Here Angle CAE and Angle EAC is same.
therefore,
m(Angle BAE)=m(Angle EAC)

or, 2x=40
or, x=20
Hence,
m(Angle EAC)=

=

Answer:
B

I had this question a few months back and I think this was the answer not too sure though
Answer:
Step-by-step explanation:
It's multiplication. Simply multiply 0.3 by 4. How multiplying dedcimals works is that we forgett the decimal until later. So, first we have 3 times 4. What's that? 12. And how many numbers did we have after the decimal? One. So, we hop over one decimal space to receave the answer 1.2. I hope I helped!!!
To simplify the given equation, you want to combine like terms. Since both terms have x^8, we can add the coefficients and leave the x^8
3x^8-7x^8 (do 3-7)
=-4x^8 so the answer is C
Hope this helps
