Ok so I will take this from the top, lets start out with choice A (-1,-12) we will need to see if the answer is equal to A. so first lets just merge these two problems into eachother to get 4x-8=2x-10 now, after subtracting 2x from each side we get 2x-8=-10. Now, add 8 to both sides which will give us 2x=-2... now it is simple, just divide -2 by 2 to get an answer for x as -1...Answer A is the correct answer
Answer:
its b 24pi
Step-by-step explanation:
To solve this problem we must know that when any two lines intersect , a pair of opposite angles from the figure Will be equal
so that means that

we can subtract twenty from each side


now we can subtract like terms

so we can get the final answer as
