All of the above. it is a three dimensional pyramid, and a "polyhedron" means it is triangular.
4x+1 = 2x+23
4x = 2x+22
2x = 22
x = 22/2 = 11
x = 11
3x-8 = 3(11)-8 = 33-8 = 25
BC=25
Answer: 6
Step-by-step explanation:
4+(x-3) = 2x-5
x+1 = 2x-5
x=6
62.831 because the firs number that is different between the two is .8 and .3, and .8 is greater regardless of the numbers that follow afterward.
-30p/6p
