The answer is plane because it is a two dimensional figure
Answer:
m = 7
Step-by-step explanation:
2m + -4 = 10
Reorder the terms:
-4 + 2m = 10
Solving
-4 + 2m = 10
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2m = 10 + 4
Combine like terms: -4 + 4 = 0
0 + 2m = 10 + 4
2m = 10 + 4
Combine like terms: 10 + 4 = 14
2m = 14
Divide each side by '2'.
m = 7
Simplifying
m = 7
Answer
y = 
Step-by-step explanation:
-10 + 2y = 7
Add 10 to both sides of the equation
2y = 7 + 10
Add 7 and 10
2y = 17
divide each term in 2y=17 by 2

Divide y by 7
y =

Answer:
x=20
Step-by-step explanation:
just use the pythagorean theorem!!
square 12 and 16 to get 144 and 256
add those together to get 400, and then just take the square root of 400 (which is 20)
this means that x=20!
hope this helps!! :)
