The sum of three numbers is 78. The second number is 10 more than the first, and the third number is two times the second number
Anestetic [448]

Step-by-step explanation:

a+b+c=78

b=10+a

c=2b

then, we back the first

a+10+a+2b=78

2a+2b=78- 10

2a+2(10+a)=68

2a+2a=48

4a=48

a=12

b=22

c=44

B in the photo

another way to write the problem:

square root is also taking the 1/2 power:

(4x)^{1/2} * (x+7)^{1/2} \\

since they are raised to the same power:

(4x * (x+7))^{1/2}\\(4x^2 + 28x)^{1/2}\\\\=\sqrt{4x^2 + 28x}
