Answer:
x = 52
Step-by-step explanation:
The square corner symbol indicates the sum of the marked angles is 90°. (They are complementary.)
(x +3)° +35° = 90°
x° = 90° -38° = 52°
x = 52
Answer:
Maybe the reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, maybe some biotic factors like animals or humans could be the reason. Maybe the humans have planted seeds there, and maybe some abiotic factors like soil could also be the reason why. And maybe the plants that grow there receive a lot of rain, or maybe the limiting factor is the rain, and the type of plants that grow there don't need much water to thrive.

Answer:
16 ft.
Step-by-step explanation:
A=LW
Area=Length times Width
We have the area and the Width.
112=Lx7
112÷7=L
L=16
The Length (n) is 16ft.
You can add the two equations together, this way you get:
5x = 25
You divide by 5:
x = 5
Now you just have to use this number in one of the original equations to get y:
x - 7y = -16
5 - 7y = -16 /subtract 5
-7y = -21 /divide by 7
-y = -3 /multiply with -1
y = 3
