Answer:
39.6
Step-by-step explanation:
i would give explanation but im bad at doing that
Multiply -3[4x+y=6].
This gets you -12x-3y=-18.
Add the two equations together to eliminate the y.
-12x - 3y = -18
+ 12x + 3y = 18
------------------------
0 = 0
This means that these are in fact the same line, therefore there are infinite solutions.
The line, shadow and the height form a right angled triangle so we can apply the Pythagoras theorem here:-
11^2 = h^2 + 8^2 where h = height of the kite
h^2 = 11^2 - 8^2
h^2 = 57
h = 7.55 ft to the nearest foot Answer
Answer:
11q-12+29
Step-by-step explanation:
Add like terms which in this case would be -5 and -7 which would equal -12. Those are the only like terms so your answer would be 11q-12+29
