• Paul has 5 pencils, each x inches in length. When she lines up the pencils end to end, they measure 34.5 inches. Select all the equations that represent this situation. A) 5 + x = 34.5
B) 5x = 34.5
C) 34.5 divided by 5 = x
D) 34.5 - 5 = x

B and C

Step-by-step explanation:

Both of these equationa can be used to find the length of each pencil

c. (3,2,6) is the answer.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
