Step-by-step explanation:
Answer:
720
Step-by-step explanation:
60×12=720 so the monthly yearly coast would be 720
Step-by-step explanation:
if you have the answer, why do you ask ?
anyway,
l = length
b = breadth
perimeter = 2×l + 2×b = 30 cm
l = b + 10
now we use this identity in the perimeter equation :
2×(b+10) + 2b = 30
2b + 20 + 2b = 30
4b = 10
b = 2.5 cm
l = b + 10 = 2.5 + 10 = 12.5 cm

Since 11√45 and 4√5 do not share a common radical, you cannot subtract them. By looking at the equation, you can see that 11√45 is not fully simplified yet by the 45 within the square root.
Breaking it up into squares, you can find that 3 x 3 x 5 = 45, which can be translated into 3<span>² x 5</span>. Since the 3 is a square component in the 45, you can now extract it. Extract the 3 by dividing it from the 45 within the square root and multiplying it into the 11.
Your result is a 33√5, which shares a common radical with 4√5. You can now subtract 33√5 and 4√5, which is 29√5.
Side note: I noticed you got the answer wrong because you chose 7√40. I presume it's because you subtracted the components individually. I suggest that you look up lessons about simplifying radicals, along with adding and subtracting them. Hope this helps!
