Answer: x = 125

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x/5 - 7 = 18

1/5x + -7 = 18

Step 2: Add 7 to both sides.

1/5x - 7 + 7 = 18 + 7

1/5x = 25

Step 3: Multiply both sides by 5.

5 * (1/5x) = (5) * (25)

x = 125

What is the solutionto the equation √x^2+2x-25=√x+5

Nadya [2.5K]

Answer:

Move

√ x +5 to the left side of the equation by subtracting it from both sides.

√ x 2 + 2 x − 25 − √ x + 5= 0

Graph each side of the equation. The solution is the x-value of the point of intersection.

x = 5

Hope this helped!! :)

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x2 + 2x = 17

yawa3891 [41]

--------------------------------------------------------
Equation Given
--------------------------------------------------------
x² + 2x = 17

--------------------------------------------------------
Add the constant to make it perfect square
--------------------------------------------------------
x² + 2x + (2/2)² - ²(2/2)² = 17

--------------------------------------------------------
Evaluate the brackets
--------------------------------------------------------
x² + 2x + (1)² - ²(1)² = 17

--------------------------------------------------------
Form the perfect square
--------------------------------------------------------
(x + 1)² - 1 = 17

--------------------------------------------------------
Add 1 to both sides
--------------------------------------------------------
(x + 1)² = 17 + 1
(x + 1)² = 18

--------------------------------------------------------
Square root both sides
--------------------------------------------------------
√(x + 1)² = $\pm$ √18

--------------------------------------------------------
Solve for x
--------------------------------------------------------
x = 4.24 - 1 or - 4.24 -1

x = 3.24 or - 5.24 (nearest hundredth)

--------------------------------------------------------
Answer: x = x = 3.24 or - 5.24
