Answer:
(a+bc)(ac+b)
Step-by-step explanation:
Step 1:
abc²+ab+a²c+b²c
Step 2:
ab+a²c+abc²+b²c
Step 3:
a(ac+b)+bc(ac+b)
Step 4:
(a+bc)(ac+b)
So your final answer is:
(a+bc)(ac+b)
Answer:
<em>Proof below</em>
Step-by-step explanation:
Let's assume a is a type 1 integer. By definition, it means we can find an integer n such that
a=3n+1
We need to prove
is a type 1 integer
Expanding

If
is a type 1 integer, then we should be able to find an integer m such as

Equating

solving for m

Since we know n is an integer, then the expression of m gives an integer also. Having found the required integer m, the assumption is proven
X=180-2(60)
=180-120
=40
The length of the other angle is 40°.
