Anyone can tell me how to calculate the square root

-18

Step-by-step explanation:

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

STEP 1: Separate The Digits Into Pairs.

STEP 2: Find The Largest Integer.

STEP 3: Now Subtract That Integer.

STEP 4: Let's Move To The Next Pair.

STEP 5: Find The Right Match.

STEP 6: Subtract Again.

(I always use these steps.)

root 324=. 18. is the right answer

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
