Answer:
A. 9.49
Step-by-step explanation:
Use Pythagorean theorem to find the distance and make a right triangle.
So then..
a² + b² = c²
3² + 9² = c²
c² = 9 + 81
c² = 90
c² = 
c = 9.49
Answer:
4
Step-by-step explanation:
-3-(-7) is the same as -3+7, which is also the same as 7-3, which is equal to 4
1.8x≤48
x≤6 (A)
2.10+x>23
x>13(B)
3.x-14≤28
x≤42(C)
4.There are no y in the inequality
5.x-4≥0
4=4,18≥4
So C and D are the answer
You distribute the -4 with the -8x and -8 which results in 32x+32.
