A(1, 1), B(7, 1), C(1, 9)
AB = 7 - 1 = 6
AC = 9 - 1 = 8
Use the Pythagorean theorem:
AB² + AC² = BC²
Substitute:
BC² = 6² + 8²
BC² = 36 + 64
BC² = 100 → BC = √100 → BC = 10
The perimeter of ΔABC:
P = 6 + 8 + 10 = 24
<h3>Answer: 24 units</h3>
The 4 1/2 gets converted to 9/2 and 4 3/4 becomes 19/4. You then multiply straight across and you shall get 21.38
Answer:
54
Step-by-step explanation:
6x - 9x = -21
-3x = - 21
x = -21 / -3
x = 7
