1. 3.14 x 4.5 x 12.5 + 3.14 x 4.5^2 = 240.21 = 240 cm^2
2. 14x(14x(sqrt(22^2+14^2)) = 561.1PI cm^2
I think x=23 because it looks like on the smaller triangle everything is divided by 3 and 23-10=13
D. Square root of 6. D is the correct answer
Answer:
Third answer.
Step-by-step explanation:
To simplify, we can factor 'x' from the equation, giving us:
However, we must put a domain restriction to ensure that the denominator will not equal 0. This means that 'x+ 4' cannot equal zero. Therefore, x ≠ -4.
The third answer is correct.
Easy! All you have to do is divide 775 by 25.
775 / 25 = 31
They will need 31 boxes of pencils to have 775 pencils in all. Hope this helps!
