Answer: C
Work:
The square root of 32 can be simplified and then combined with the square root of 2 into one single term. Since 32 is divisible by 16, which is the square root of 4, the term then becomes 4(square root of 2).
You then have 4(square root of 2) + (square root of 2) as your expression which simplifies to be equal to 5(square root of 2). The answer is then C.
Answer:
1) James brother is 10-x years old
2) James was 3 years ago x-3 years old
3) James brother was 3 years ago 7-x years old
4) 3(x-3)=7-x
5) James is 4 years old, his brother is 6 years old
Step-by-step explanation:
3) 10 - x - 3 = 7 - x
5) 3* James age 3 years ago = James brothers age 3 years ago
<=> 3*(x-3) = 7-x
<=> 3x - 9 = 7 - x
<=> 4x = 16
<=> x = 4
C would be the correct answer
A would mean that 6=3*18, which is incorrect
B would mean that 3=6*18 which is also incorrect
C would mean that 18=6*3 which is CORRECT
D would mean that 18=6*2 which is also incorrect
Therefore, C would be the correct answer

Answer:
√13
Step-by-step explanation:
There's a formula called the distance formula that is based on the Pythagorean theorem. It is used to find the distance between points in 2 (or more) dimensions.
The distance (d) between points (x1, y1) and (x2, y2) is ...
d = √((x2-x1)^2 +(y2-y1)^2)
___
To find the distance you're looking for, fill in the values in the formula and do the arithmetic.
d = √((6-3)^2 +(5-7)^2) = √(3^2 +(-2)^2)
d = √(9 +4)
d = √13
The distance between the given points is √13.
