<h2>(x, y) = (x, 2 + 5/6 x)</h2>
Step-by-step explanation:
-5x + 6y = 12
y = 5/6x + 2
<h2>_______________</h2>
-5x + 6y = 12
-5x + 6(5/6x + 2) = 12
-5x + 5x + 12 = 12
x real numbers
(x, y) = (x, 2 + 5/6 x)
Step-by-step explanation:
area of quadrilateral = sum of area of triangles
area of triangle ADC = .5 * b * h
= .5 * 12 * 5 = 30 km^2
area of ∆ABC = .5 * sinx* ab* ac
= .5 * sin 30 * 3* 13 = 39/4 = 9.75 km^2
area of quadrilateral = 39.75 km^2
total cost =$ 397.5 million
I think it’s 55 I think not to sure but ya it’s that
