Answer:
Step-by-step explanation:
Multiply through the 3 of the first bracket to get 3m +12. Then multiply out the second bracket by -2 to get -8m -2.
Write it out in a line: 3m + 12 - 8m -2
Simplify: -5m +10
Divide by -5 again to simplify further: m - 2
=7m+30
Distribute:
=(3)(m)+(3)(2)+(4)(6)+(4)(m)
=3m+6+24+4m
Combine Like Terms:
=(3m+4m)+(6+24)
The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
1/3 is less than 2/3
7/9 is greater than 2/3
4/10 is less than 2/3
4/6 is equal to 2/3
34/100
