Midpoint of a line segment 

Answer: 1763
Step-by-step explanation:
Split this shape into three spaces, to where there are two square-like shapes above one rectangular shape. Next you will find the area of all three separate shapes and add them up to get your total area.
23m times 12m = 276,
23m times 12m = 276,
31m - 12m = 19m, (Here, we are taking the amounts we know of our rectangular shape to get the formula L times W used for determining this shape's area. We use the length of one of the squares(12m) subtracted by the length of both the rectangular shape and one of the squares.(31m) What we get is the lone value of L.
69m times 19m = 1311.
Add 276 + 276 + 1211. Answer = 1763.
Answer:
the terms are 400n , 62n 120 and 8n
the number of coefficients is 3
equa expression is 346n+120
Step-by-step explanation:1
Combining like terms 400n400n and -62n−62n
338n+120+8n
338n+120+8n
2 Combining like terms 338n338n and 8n8n
346n+120
346n+120
For the rest of them i just counted.
Use elimination
-x - y = -9
x - y = 3
Add both equations
-2y = -6, y = 3
-x -(3) = -9
-x = -6, x = 6
Final answer: x = 6, y = 3
