Answer:
Step-by-step explanation:
Given that segment BC is the base of the triangle, this drawing shows that triangle ABC is an equilateral triangle.
Since;
<B = <C = 60°
Then,
<A + <B + <C = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
<A + 60° + 60° = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
<A =
- ![120^{o}](https://tex.z-dn.net/?f=120%5E%7Bo%7D)
= 60°
Thus,
AB = BC = AC = 6 inches
The construction is attached to this answer.
Yea so I don’t know sorry
Answer: ![||cu||=39](https://tex.z-dn.net/?f=%7C%7Ccu%7C%7C%3D39)
Step-by-step explanation:
Given
and ![c=-3](https://tex.z-dn.net/?f=c%3D-3)
is a vector with 3 times the vector u in opposite direction
![|u|=\sqrt{5^2+(-12)^2}\\|u|=\sqrt{25+144}\\|u|=13](https://tex.z-dn.net/?f=%7Cu%7C%3D%5Csqrt%7B5%5E2%2B%28-12%29%5E2%7D%5C%5C%7Cu%7C%3D%5Csqrt%7B25%2B144%7D%5C%5C%7Cu%7C%3D13)
![\therefore ||cu||=|3\times 13|\\\Rightarrow ||cu||=39](https://tex.z-dn.net/?f=%5Ctherefore%20%7C%7Ccu%7C%7C%3D%7C3%5Ctimes%2013%7C%5C%5C%5CRightarrow%20%20%7C%7Ccu%7C%7C%3D39)
option (a) is correct.

A) -20
Step-by-step explanation:
distribute the 4y and the -4 to the parentheses
16y^2 -16y+16y-20-16y^2
