Answer:
- 5m + 8
Step-by-step explanation:
Given:
(2m + 3) - (7m - 5)
If you want to find the differences between two values, it means you are to subtract
(2m + 3) - (7m - 5)
This means subtract (7m - 5) from
(2m + 3)
Step 1: Open parenthesis
(2m + 3) - (7m - 5)
= 2m + 3 - 7m + 5
Group like terms
= 2m - 7m + 3 + 5
= - 5m + 8
Or
= 8 - 5m
Sry idk wish I could know but good luck

We can find h by calculating the area S of the parallelogram in two ways. We can write:

. On the other hand,

. Then:
You have to use the formule: y2-y1/x2-x1
-2-(-2)/4-(-3)=0/7
