Answer:
a≥0
Step-by-step explanation:
a-82≥-82
a≥-82+82
a≥0
Answer:
x-5=sqrt(2x+5)
then square both sides
x2-10x+25=2x+5
x2-8x+20=0
rest is trivial

Answer:
the radius is half of O
Step-by-step explanation:
Solution:
Let the three consecutive multiples of 4 be 4x, 4(x+1) and 4(x+2)
Then we can write
![4x+4(x+1)+4(x+2)=52\\ \\ x+x+1+x+2=52/4\\ \\ 3x+3=13\\ \\ 3x=10\\ \\ x=\frac{10}{3}\\](https://tex.z-dn.net/?f=%204x%2B4%28x%2B1%29%2B4%28x%2B2%29%3D52%5C%5C%20%5C%5C%20x%2Bx%2B1%2Bx%2B2%3D52%2F4%5C%5C%20%5C%5C%203x%2B3%3D13%5C%5C%20%5C%5C%203x%3D10%5C%5C%20%5C%5C%20x%3D%5Cfrac%7B10%7D%7B3%7D%5C%5C%20)
As 10/3 is not a multiple of 4. Hence no consecutive multiples are possible.
