Two triangle areas of:
10*24/2+18*24/2
120+216
336 u^2
It's 248 ft because it increased by 24%, you do 200 ft times 1.24 to get 248 ft.
Answer:
Substitute the w‘s in the equation for 2.
8(2)^2+8(2)+9
32+16+9
57
:)
Multiply first equation by 8,
24x + 40y = 352
Multiply second equation by 3,
24x - 21y = -75
Now, subtract second from 1st,
61y = 427
y = 427/61
y = 7
Substitute it in very first equation,
3x + 5(7) = 44
3x = 44 - 35
x = 9 / 3
x =3
In short, Your Answer would be Option D) (3, 7)
Hope this helps!
