Let's solve together :)
Solving for a.
First, add 56 to both sides to get this:
8ab+2a=−56b+6
Factor out variable "a".
a(8b+2)=−56b+6
Divide both sides by 8b+2.
a = -28b+3 / 4b+1
Have a great day. :)
Answer:1 four
Step-by-step explanation:
this is a triangular pyramid which means it hasa triangle shape base which counts as one and it has one face on each side of the triangular base which is three more so if you addthe one face which is the base and the three sides it gives you four faces
