Calculate circumference. You can do the math mentally with area & perimeter,but circumference is much more complex
I want to say 5 but I'm not sure
It is -11x + 24 because you multiply the numbers in the parentheses by 3 then collect like terms 10x +24 - 21x then you do 10x minus 24x and you get -11x+24
Answer:
i belive 11 and 1 sorry if it is not right
Step-by-step explanation:
This is a right angle triangle.
So, by Pythagoras theorem,
√(32^2+20^2) = x
or √(1024+400) = x
or √1424 = x
or <em>37.74 = x</em>
