1 answer:

8 0

All real numbers

distribute (x+6)(x+3) to get x^2+6x+3x+18

your equation now looks like this:

x^2+6x+3x+18= x^2+6x+3x+18

because the equations are equal, the answer is all real numbers

Two investments totallng $47,500 produce an annual income of $3000. One investment ylelds 9% per year, while the other yields 6%

enot [183]

Answer:

The correct answer is "$5000".

Step-by-step explanation:

The given values are:

Two investments totaling,

= $47,500

Annual income,

= $3000

One investment yields per year,

= 9%

Other yield,

= 6%

Let,

The amount invested in 9% will be "x".
The amount invested in 6% will be " $47,500-x$ ".

Now,

⇒ $0.09x+0.06(47,500-x)=3000$

⇒ $0.09x+2850-0.06x=3000$

⇒ $0.03x+2850=3000$

⇒ $0.03x=150$

⇒ $x=\frac{150}{0.03}$

⇒ $x=5000$

How many square feet are in 100 m squared

Vikentia [17]

Answer:

100 Sq Mt = 1135.69 Sq Ft

Step-by-step explanation:

We are required to find how many square feet are in 100 m squared.

1 meter = 3.37 ft

1 metre x 1 meter = 3.37 x 3.37 Sq ft

1 Sq Mt = 11.3569 Sq ft

100 sq Mt = 100 x 11.3569 sq ft

100 sq mt = 1135.69 Sq ft

Hence

100 Sq Mt = 1135.69 Sq Ft
