Answer:
<h3>
BC = 29</h3>
Step-by-step explanation:
Point B is between A and C and the points A, B, and C are collinear so:
AB + BC = AC
487 + 5x + 8x + 709 = 91
13x + 1196 = 91
- 1196 - 1196
13x = - 1105
÷13 ÷13
x = - 85
BC = 8x + 709 = 8(-85) + 709 = - 680 + 709 = 29
Answer: x =3
Step-by-step explanation:
2× 3 = 6
length= 5 inches
width= 2×3= 6 inches
2(l+w) = 2(5+6)
2(11)
2×11= 22
hope this helps:-)
Two lines and a point are guaranteed to be coplanar if the two lines share only a single point.
Hope this helped :)
Answer:
Step-by-step explanation:
a² + b² = c²
a² + 9² = 12²
a² + 81 = 144
a² = 63
a = √63
Why would someone give you the answer if you are in detention? I will tell you the first step which is to get rid of the -3 by adding positive three to both sides of the equation. Then from there, you should know what to do! Pay attention in class, and stop giving your teacher trouble!
