Answer:
It's 19.
Step-by-step explanation:
Use order of operations (PEMDAS):
2^2[4+(3-6)^2]-13
Parentheses first:
= 2^2[4 + (-2)^2] - 13
= 2^2 ( 4 + 4) - 13
= 2^2 * 8 - 13
Now work out the exponent:
= 4*8 - 13
Now the multiplication:
= 32 - 13
= 19.
Answer: The answer is the diameter.
Step-by-step explanation:
1) 4x + 2 = 1/2x + 17
2) 4x - 1/2x = 17 - 2
3) 3.5x = 15
4) (3.5x)/3.5 = 15/ 3.5
5) x = 4.29 (rounded)
