An equation is formed of two equal expressions. The original height of the water in the pool in feet is 5.

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Given the equation, 4.75 = x + (-0.25) can be used to find x, the original height of the water in a pool. Therefore, the height of the fool in the beginning is,

4.75 = x + (-0.25)

4.75 + 0.25 = x

x = 5

Hence, the original height of the water in the pool in feet is 5.

Solving the equation $2x^2-12x+6=0$ using completing square method we get $(x+3)^2=6$

So, Option A is correct.

Step-by-step explanation:

We need to solve the equation $2x^2-12x+6=0$ using completing square method.

Solving using completing square method

$2x^2-12x+6=0$

For completing the square we need to make formula a^2-2ab+b^2=(a-b)^2

Divide the equations by 2

$x^2-6x+3=0$

$x^2-6x+3=0$

Adding and subtracting (3)^2 on both sides.

$(x)^2-2(x)(3)+(3)^2-9+3=0$

$(x+3)^2-6=0$

$(x+3)^2=6$

Solving the equation $2x^2-12x+6=0$ using completing square method we get $(x+3)^2=6$

So, Option A is correct.

A 10-foot ladder leans against the side of a house with its base 2.2 feet from the house. Use the Pythagorean Theorem to approxi

sergejj [24]

Answer:

Ladder reaches 9.76 high.

Step-by-step explanation:

From the figure attached,

Ac is the ladder which reaches at the point A when leans against the side of a house.

Length of the ladder = 10 feet

Distance of the ladder form the base of a house = 2.2 ft

By Pythagoras theorem,

AC² = AB² + BC²

(10)² = h² + (2.2)²

h² = 100 - 4.84

h = √95.16

h = 9.755 feet

≈ 9.76 feet

Therefore, the ladder reaches the 9.76 high.
