I think the answer is C hope this would help you
and
are vectors and:
![\vec{u}=14j=0i+14j=[0,14]\\\\ \vec{v}=i+4j=1i+4j=[1,4]](https://tex.z-dn.net/?f=%5Cvec%7Bu%7D%3D14j%3D0i%2B14j%3D%5B0%2C14%5D%5C%5C%5C%5C%0A%5Cvec%7Bv%7D%3Di%2B4j%3D1i%2B4j%3D%5B1%2C4%5D)
is the dot product or scalar product, so:
![\vec{u}\cdot\vec{v}=[0,14]\cdot[1,4]=0\cdot1+14\cdot4=56](https://tex.z-dn.net/?f=%5Cvec%7Bu%7D%5Ccdot%5Cvec%7Bv%7D%3D%5B0%2C14%5D%5Ccdot%5B1%2C4%5D%3D0%5Ccdot1%2B14%5Ccdot4%3D56)
Correct answer is A.

Answer:
55/54
Step-by-step explanation:
The answer is p = 5.
Here are the steps I did.
1. Simplify 8p + 10p - p - 8p + 5 to 9p + 5 ( 9p + 5 = 50)
2. Subtract 5 from both sides ( 9p = 50 - 5)
3. Simplify 50 - 5 to 45 ( 9p = 45)
4. Divide both sides by 9 ( 45/9)
5. Simplify 45/9 to 5 ( p = 5)
