Answer:
5/9
Step-by-step explanation:
Experimental was what actually happened.
Theoretical was what should happen in a perfect, equal world.
E: 6/6 = 1
T: 4/9
E-T= 1-4/9=5/9
from the equal angles it is an isosceles triangle, AB = AC.
4x + 1 = 2x + 23
4x - 2x = 23 - 1
2x = 22
x = 22 : 2
x = 11
----------------------
4 * 11 + 1 = 2 * 11 + 23
45 = 45
--------------
now we find BC
3x - 8
3 * 11 - 8 =
25 (is the value of BC)
14/32 is left because you subtract 32 by what was eaten and out your answer over what was there before some of it got eaten.
Answer:
Area = length × width
72 = 9 × width
8 = width (9 × 8 = 72)
pertinter = length + width + length + width
= 9 + 8 + 9 + 8
perimeter = 34
