Answer: a=-1

Step-by-step explanation:

-11-5a=6(5a+4)

-11-5a=30a+24

-11-5a-30a=24

-5a-30a=24+11

-35a=35

a=-1

-11-5a=6(5a+4) .... Distribute the 6 to 5a and 4
-11-5a=30a+24 .... Subtract 30a from both sides
-11-5a-30a=24 .... Add 11 from both sides
-5a-30a=24+11 .... Add like terms
-35a=35 .... Divide -35a from both sides
a=-1 .... Final answer

What is the completely factored form of f(x)=x3+5x2+4x−6?

Gre4nikov [31]

$f(x)=x^3+5x^2+4x-6$
$f(-3)=(-3)^3+5(-3)^2+4(-3)-6=0\implies x+3\text{ is a factor of }f(x)$

Synthetic division yields

-3 | 1   5   4   -6
.    |      -3 -6    6
- - - - - - - - - - - - -
.    | 1   2 -2    0

which translates to

$\dfrac{x^3+5x^2+4x-6}{x+3}=x^2+2x-2$

with remainder 0. Now by the quadratic formula,

$x^2+2x-2=0\implies x=\dfrac{-2\pm\sqrt{2^2-4(1)(-2)}}2=-1\pm\sqrt3$

and so

$f(x)=x^3+5x^2+4x-6=(x+3)(x-(-1+\sqrt3))(x-(-1-\sqrt3))$

(PLS HURRY ASAP 100 POINTS)

Sophie [7]

Answer:

D) 0.3125

====================

Total number of outcomes is 16, count of all outcomes.

Number of outcomes with 3 or more tiles is 5:

HTTT, THTT, TTHT, TTTH, TTTT

The probability is:

P = favorable outcomes / total outcomes
P(at least 3 tails) = 5/16 = 0.3125

Correct choice is D.
