What is the exact value for the expression the square root of 56. − the square root of 14. + the square root of 126.? Simplify i
solong [7]
Factor a square root of 14 out of every expression to get:

\sqrt{14}*(\sqrt{4}-1+\sqrt{9)

\sqrt{14}*(2-1+3)

4*\sqrt{14}

Thus, the expression is equal to four times the square-root of 14.  The second answer is correct.

Write a problem situation to match the inequality: x divided by 4 less than or equal to 5
Paha777 [63]

Answer:

yes it is ill explain

Step-by-step explanation:Find the student's error in solving the following inequality.31 < -5x + 625 < -5x-5 < x

The student should have added 6 to both sides instead of subtracting it.

The student divided 25/-5 incorrectly.

The student should have switched the direction of the inequality sign to get -5> x for a final answer.

The student should have switched the direction of the inequality sign to get -5> x for a final answer.

Find the student's error in solving the following inequality.2 < -3x -4 < 56 < -3x < 5-2 > x > -5/3

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

The student divided 6/-3 incorrectly.

The student should not have switched the direction of the sign in the final step.

The student should have added 4 to all parts (left, middle, and right) to get 6 < -3x < 9.

Step 3: Multiplication property

Which numbers are solutions to the inequality 2x - 1 > x + 2? Check all of the boxes that apply.

4, 5

If x < 5 and x > c, give a value of c such that there are no solutions to the compound inequality. Explain why there are no solutions

Sample response: The value of c could be 5 or any number greater than 5.

The solution is the intersection of both solution sets of the given inequalities.

The solutions of the compound inequality must be solutions of both inequalities.

A number cannot be both less than 5 and greater than 5 at the same time.

Identify the graph of the inequality 2(2x - 1) + 7 < 13 or -2x + 5 -10.

Find the value of x (4x+7) 97 (17x+13)
zysi [14]

Answer:

4x^2 +1656x + 1261

Step-by-step explanation:

X multiply by 4x is 4x^2 (4x squared)

x multiply by 7 is 7x

4x^2+7x

97 x 17x is 1649x

97 x 13 is 1261

1649x+1261

4x^2 + 7x + 1649x + 1261

1649x + 7x is 1656x

4x^2 +1656x + 1261
