Step-by-step explanation:
2 x pi x radius which is half of 18 so 9 is about 5.487 and rounded to the nearest hundredth is 56.55.
Answer:
7x + 33 -I could be wrong I'm not an expert in maths jus trying to help
Step-by-step explanation:
x + 13 9x-7
so first you need to times both by two because there are two of both sums
2(x+13) so you times both numbers by 2 so
= 2x+26
and do the same with 9x - 7 so
2(9x-7) = 18x - 14
and then you add them together and find the like terms.
Like terms means for example in the equation:
2x + 3x - 4 + 3
the like terms are the two numbers that are the same like 2x and 3x are the same since they are both the same term and since there is a plus sign before the 3x you add them so 5x and then you need to do -4 + 3 = 7 and so the answer is 5x + 7.
In this case its:
2x + 26 + 5x + 7. So the like terms are 2x and +5x and +26 and +7.
So 2x + 5x = 7x and 26 + 7 = 33.
So the final equation is 7x + 33
Hope this helps :D
By definition, whole numbers will never be negative. They are the numbers we count with but include 0. -4 is not a whole number.
