Simplify 7x + 2y = -23
Solving
7x + 2y = -23
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = -23 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = -23 + -2y
7x = -23 + -2y
Divide each side by '7'.
x = -3.285714286 + -0.2857142857y
Simplifying
x = -3.285714286 + -0.2857142857y
56 is what I got.
Hope this helps
P=44+66+88/2=198/2=99
With Heron formula:
S=root 99*(99-44)(99-66)(99-88)=root 99*55*33*11=root 1976535= 1405.8929.....=1405.9
The figure is a rectangle so the formula is area = length *width
So the area is 432
