Answer:
Bottom right. It's correct
Answer: x= 1/5
3/4x +1/4 =2x
1/4= 1 1/4x or 1.25x (minus 3/4x on both side)
1/5=x
The question ask to find the angle between the given vector to the nearest tenth of a degree and base on the value or the coordinates of each vector, the possible value of the angle base on the said vectors is 1.8 degree. I hope you are satisfied with my answer and feel free to ask for more
I'm pretty sure the 3rd one is right, use a calculator
Answer:
4Z+16-Z²
Step-by-step explanation:
Given that,
D = Z+6
C = -2 + Z - Z²
We need to find the value of 3D+C.
So,
3D+C = 3(Z + 6)+(-2 + Z - Z²)
= 3Z+18-2+Z-Z²
= 4Z+16-Z²
So, the required expression is 4Z+16-Z².
