On combine like terms, we get

Using addition property of equality, add 2x on both sides.

Using subtraction property of equality, subtract 7 from both sides.

Using division property of equality, divide both sides by 20.


Therefore, the required reasons are:
2. Distributive property
3. Combining like terms
4. Addition property of equality
5. Subtraction property of equality

Answer:
85.1 (I think)
Step-by-step explanation:
2×2=4
5×2=10
5×6=30
(3×10)÷2=15
3squared+10squared=√109=10.44
5×10.44=52.2÷2=26.1
26.1+4+10+30+15=85.1
