Answer:
72m2
Step-by-step explanation:
first you find out what 6*6*4=144+8*6*6=288-144=144/2=72m^2
Answer:
x = 35
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 6, thus
sum = 180° × 4 = 720°
Sum the given angles and equate to 720
4x - 5 + 117 + 3x - 3 + 3x + 6 + 118 + 4x - 3 = 720, that is
14x + 230 = 720 ( subtract 230 from both sides )
14x = 490 ( divide both sides by 14 )
x = 35
Answer:
(-1,-3)
Step-by-step explanation:
The given system of equations is;

and

Let us equate the two equations to get;

Group similar terms;

Simplify;

Divide both sides by 9.

Put x=-1, into any of the equations, say (2);



The solution is;
(-1,-3)
