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

What are the real zeros of x^3+4x^2-9x-36
Katyanochek1 [597]

Answer:

x = -4\\x = -3\\x = 3

Step-by-step explanation:

To find the real zeros you must match the function to zero and factor the expression.

We have a polynomial of degree 3.

We try to group the terms to perform the factorization

x ^ 3 + 4x ^ 2-9x-36 = 0\\\\x ^ 2(x + 4) - 9(x + 4) = 0

Now we take (x + 4) as a common factor

(x + 4)(x ^ 2 -9) = 0

If we have an expression of the form (a ^ 2-b ^ 2) we know that this expression is equivalent to:

(a ^ 2-b ^ 2) = (a + b)(a-b)

In this case

a = x\\b = 3

So:

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

Finally:

x ^ 3 + 4x ^ 2-9x-36 = (x + 4)(x + 3)(x-3) = 0

The solutions are:

x = -4\\x = -3\\x = 3
