What is 9(6+5x)-x(x-1) simplified

1 answer:

4 0

Apply the distributive property.

9(6 + 5x) - x(x - 1) =
54 + 45x + -x^2 + x =
54 + 46x + -x^2

So, 54 + 46x + -x^2 is the answer.

HELP!!! Use the factor Theorem to determine whether the binomial x+1 is a factor of the polynomial function f(x) =2x^3-9x^2+13x-

Dovator [93]

ANSWER

A. No because f(c)=-30

EXPLANATION

The given polynomial is

$f(x) =2x^3-9x^2+13x-6$

If x+1 is a factor , then f(-1) must evaluate to zero.

$f( - 1) =2( - 1)^3-9( - 1)^2+13( - 1)-6$

$f( - 1) =2( - 1)-9( 1)+13( - 1)-6$

$f( - 1) = - 2-9 - 13-6$

$f( - 1) = -11 - 19$

$f( - 1) = - 30$

Since f(-1) is not equal to zero, x+1 is not a factor of

$f(x) =2x^3-9x^2+13x-6$

Which type of triangle has one angle with a measurement greater than 90°?

masya89 [10]

Answer:
Obtuse-angled triangle

Explanation:
Triangles can be classified based on the measures of their angles as follows:
1- Right-angled triangle: Triangle that has one of its angles = 90°
2- Acute-angled triangle: Triangle that has all of its angles less than 90°
3- Obtuse-angled triangle: Triangle that has one of its angles greater than 90°

The attached image shows an obtuse-angled triangle. We can note that measure ∠B is greater than 90°

Hope this helps :)
