Answer:
The length of AB is units
Step-by-step explanation:
The rule of the distance between two points (x1, y1) and (x2, y2) is
∵ The endpoints of AB are (-4, 5) and (2, -7)
→ Let point (-4, 5) be (x1, y1) and point (2, -7) be (x2, y2)
∴ x1 = -4 and y1 = 5
∴ x2 = 2 and y2 = -7
→ Substitute them in the rule above to find the length of AB
∵
∴
∴
∴ The length of AB is units
Answer:
answer is subtract the 180-120=80
Answer: The missing side length is 5yd's and the perimeter is 84
Step-by-step explanation:
2 is more than a number v
2 > v is your equality
this means that <em>v</em> can be the number 1 or less

-2n-24=-8(2n-4)
Multiply both sides by -1
2n+24=8(2n-4)
Distribute the right side
2n+24=16n-32
Subtract 2n from both sides
24=14n-32
Add 32 to both sides
56=14n
Divide 14 from both sides
n=4
