Step-by-step explanation:
m > n <em>add 2.1 to both sides</em>
m + 2.1 > n + 2.1 TRUE
m > n <em>subtract (-4) from both sides</em>
m - (-4) > n - (-4) TRUE
m > n <em>add 16.5 to both sides</em>
16.5 + m > 16.5 + n TRUE
m > n → 3 + m > n <em>logic</em>
3 + m > n <em>add 6 to both sides</em>
9 + m > 6 + n TRUE
Answer:
16 m^2
Step-by-step explanation:
The area of a trapezoid is given by
A = 1/2 (b1+b2) *h
= 1/2 ( 6+10) * 2
= 16 m^2
Negative numbers aren't in a solution set because in equations and inequalities you have to multiply and divide and a positive number divided by a negative number will be a negative number. Positive divided by positive will be positive. Negative divided by negative will be positive. So that's why negative numbers aren't a solution to any set or equation.
