Step-by-step explanation:
triangle area is bh/2
(10 x 22)/2=110
area of big rectangle is
length x width=area
19 x 9=171
area of smaller rectangle is
length x width = area
9 x 6=54
add up all areas
110+171+54=335
Hope that helps :)
The answer is x = 3, y = -2
The system of equations is:
3x - y = 11
2x + 5y = -4
_________
Rewrite the first equation:
y = 3x - 11
_________
Substitute y in the second equation and solve x:
2x + 5(3x - 11) = -4
2x + 5 * 3x + 5 * (-11) = -4
2x + 15x - 55 = -4
17x = 55 - 4
17x = 51
x = 51 / 17
x = 3
_______
Substitute x in the equation: y = 3x - 11
y = 3 * 3 -11
y = 9 - 11
y = -2
