Answer:

11, square with side length of 11 units

Step-by-step explanation:

We know that to find the area of a triangle you follow this formula :

$1/2bh$

The area of this triangle is 121 ( 22 * 11 * .5)

And we know that the formula for the area of a square is

$length * width$

We also know that all sides of a square are the same length, so we can use the equation of

$Length^2 =area$

We can now substitute the area of the triangle in for the area of the square.

$Length^2 =121$

Find the square root of both sides

$\sqrt{length^2} = \sqrt{121}$

Simplify

$length=11$

PLEASE HELP what is 30th term of -12, -3, 6, 15

hoa [83]

Answer:

249

Step-by-step explanation:

We can see that the difference of every term in the given sequence is 9, because -12 + 9 = -3, -3 + 9 = 6 and 6 + 9 = 15. We may therefore assume that the sequence is arithmetic (a fancy word of saying that a sequence is increasing with a constant value every term).

Since the difference of every term is 9, we know that the explicit form of the sequence (where the value of every term is expressed in terms of the term number) is in the form $9n+c$ , where $n$ is the term number and $c$ is a constant we are going to figure out right now.

We know that the first term of the sequence is -12, so we see that $9(1) + c = -12$ and hence $c=-21$ . Therefore, the 30th term of the sequence is $9(30) - 21 = 249$ .

Two roots of a third degree polynomial function f(x) are -4 and 4. Which statement describes the number and nature of all

Natasha2012 [34]

Answer:

f(x) has three real roots.

Step-by-step explanation:

f(x) has three real roots.

A third degree polynomial function with real coefficients has exactly 3 roots.

Furthermore, all complex roots come in pairs, either there is none, or there are exactly two conjugates, which are in the form e1+i(e2) and e1-i(e2) where e1 and e2 are polynomial expressions.

This also means that a third degree polynomial with real coefficients has at least one real root, or three.

Since we are given two real roots for the given polynomial, the third root cannot be complex alone, so the only possibility is that there are three real roots.
