Step-by-step explanation:
4ab(a-b)+b(2b-2a^2)
=4*1*-1[1-(-1)]+(-1){2(-1)-2*1^2}
=-4(1+1)-1{-2-2}
=-4*2-1(-4)
=-8+4
=-4
Answer:
The answer is 3.64m
This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 30= 3/h. You divide cos 30 by 3 and you get the answer of 3.64m rounding to 2 decimal places.

18 miles = ?
We know that 1 mile is equal to 1.6 kilometers.
Multiply 18 by 1.6 which is 28.8 kilometers.
18 miles/hour = 28.8 kilometers/hour
If you go 28.8 kilometers in one hour, how many km do you go in 5 hours.
Multiply 28.8 by 5 = 144
In 5 hours you go 144 kilometers.
