What is the simplified form of the following expression? 5 StartRoot 8 EndRoot minus StartRoot 18 EndRoot minus 2 StartRoot 2 En
qaws [65]

The simplified form of the given expression is 5\sqrt{2}.

Given expression,

5\sqrt{8} - \sqrt{18}  - 2 \sqrt{2}.

We have to simplify the above expression.

So, 5\sqrt{8} - \sqrt{18}  - 2 \sqrt{2}\\

First solve for the square root,

5\sqrt{2\times2\times2}  -\sqrt{3\times3\times2} -2\sqrt{2} \\\\10\sqrt{2} -3\sqrt{2}-2\sqrt{2}  \\

7\sqrt{2} -2\sqrt{2}

5\sqrt{2}

Hence the simplified form of the given expression is 5\sqrt{2}.

8x<br> 6x<br> 7. Solve for x.*
jarptica [38.1K]

Answer:

X = {0, -1.166666667}

Step-by-step explanation:

Simplifying

8X(6X + 7) = 0

Reorder the terms:

8X(7 + 6X) = 0

(7 * 8X + 6X * 8X) = 0

(56X + 48X2) = 0

Solving

56X + 48X2 = 0

Solving for variable 'X'.

Factor out the Greatest Common Factor (GCF), '8X'.

8X(7 + 6X) = 0

Ignore the factor 8.

Subproblem 1

Set the factor 'X' equal to zero and attempt to solve:

Simplifying

X = 0

Solving

X = 0

Move all terms containing X to the left, all other terms to the right.

Simplifying

X = 0

Subproblem 2

Set the factor '(7 + 6X)' equal to zero and attempt to solve:

Simplifying

7 + 6X = 0

Solving

7 + 6X = 0

Move all terms containing X to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + 6X = 0 + -7

Combine like terms: 7 + -7 = 0

0 + 6X = 0 + -7

6X = 0 + -7

Combine like terms: 0 + -7 = -7

6X = -7

Divide each side by '6'.

X = -1.166666667

Simplifying

X = -1.166666667

Don't get mad if it is wrong I had to do the math fast.
