Answer:
The answer is D
Step-by-step explanation:
Look at the number line and write down the coordinates.
Then plot them on a coordinate plane.
15.8m
Your perimeter is given by the sum of four sides of the rectangle:
Perimeter = 3.7m*2 + 4.2m*2 = 7.4m + 8.4m = 15.8m
Alright, so first we'll have to get y on the other side
So
2x+y=-9
-y -y
+9 +9
2x+9=-y
Then divide is all by -1 so y is positive
-2x-9=y
11.25 // 11
15×0.75
Answer: 63 cm squared
9*7=63
