Given:

The equation is

9x^2-12x+4=49

To find:

The equation after first step to solve the given equation by using square root property.

Solution:

We have,

9x^2-12x+4=49

It can be written as

(3x)^2-2(3x)(2)+(2)^2=49

(3x-2)^2=49            [\because (a-b)^2=a^2-2ab+b^2]

Therefore, the equation can be rewritten in first step as (3x-2)^2=49.

Answer:

It would be 78.539...

Step-by-step explanation:

So the equation for area is π r^2. We don't have the radius but we have the diameter. Since the radius is always 1/2 of the diameter, simply divide 10/2 to get this.

Now with the radius, it can simply be plugged into the equation for the answer:

π r^2,

π 5^2,

π 25

hjlf

Answer:

4 11/16 m²

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

From the question:

Length = 1 1/4 m

Width = 3 3/4m

Area of the rectangle =

1 1/4 m × 3 3/4 m

= 5/4 m × 15/4 m

= 75/16 m²

= 4 11/16 m²

Area of the rectangle = 4 11/16 m²
