768*3+9600 is the answer
= 2304+9600
= €11904
One of the requirements of a rectangle is that it must have four right angles ( a right angle is 90 degrees) so you just multiply 90 by 4 and you get 360 degrees
Answer is 42 because 9×5 is 45 then you have to subtract 45-3 which equals 42
5.5x+13.5y=40
x+y=5.8
x=5.8-y
5.5(5.8-y)+13.5y=40
31.9-5.5y+13.5y=40
8y=8.1
y=1.0125 or about 1.0 hours
x=4.7875 or about 4.8 hours
Answer:
166 m^2
Step-by-step explanation:
The enclosing rectangle is 9m by 29m, so is 261 m^2. From that, the white space of 5m by 19m = 95 m^2 must be subtracted. The result is that the shaded area is ...
261 m^2 -95 m^2 = 166 m^2
