Answer:
400 cm squared
Step-by-step explanation:
Since a square has all equal sides, this would mean the the all the other sides are 20 as well. To get the area, you would just multiply 20 by 20 to get 400. :)
Answer:
see explanation
Step-by-step explanation:
the 3 consecutive even integers are x , x + 2 and x + 4 , then their sum is
x + x + 2 + x + 4 = 72 , that is
3x + 6 = 72 ( subtract 6 from both sides )
3x = 66 ( divide both sides by 3 )
x = 22
x + 2 = 22 + 2 = 24
x + 4 = 22 + 4 = 26
the 3 consecutive even integers are 22, 24 , 26
Answer:
e=-1/2
Step-by-step explanation:
4/3=-6e-5/3
Multiply both sides by 3:
4=-18e-5
Add 18e to both sides:
18e+4=-5
Subtract 4 from both sides:
18e=-9
Divide both sides by 18:
e=-1/2

Answer:
x = 155°
Step-by-step explanation:
Adjacent angles of a parallelogram are supplemenary angles . Supplemwntary angles are the angles whose sum is 180°. So,
KGH + JKG = 180°
=> 25° + x° = 180°
=> x = 180 - 25 = 155°
Simplify the left side. 0.02x+(40-0.1x)=0.42x
-0.08x+40=0.42
since 0.42x contains the variable to solve for, move it to the left side of the equation by subtracting 0.42x from both sides
-0.08x+40-.0.42x=0
-0.5x=-40
x=80
