Answer:

<h2><em><u>x</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>39</u></em><em><u>°</u></em></h2>

Step-by-step explanation:

As per condition,

3x - 17° + 2x + 2° + 90° + 90° = 360°

<em>[</em><em>Since</em><em> </em><em>angle</em><em> </em><em>sum</em><em> </em><em>property</em><em> </em><em>of</em><em> </em><em>quadrilateral</em><em>]</em>

=> 3x + 2x - 17 + 2 + 90 + 90 = 360

=> 5x = 360 + 17 - 2 - 90 - 90

=> 5x = 195

$= > x = \frac{195}{5}$

=> <em><u>x = 39 (Ans)</u></em>

Hello!

Equation: $x^3=-115$

To solve, we will need to take the roots:

$x = (-115)^{(\frac{1}{3} )}$

Answer:

$x=-\sqrt[3]{115}$ or $x=-4.862944$

1) What is the GCF for the polynomial 4x3 - 2x2y?

Dafna1 [17]

(1)the GCF for the polynomial $4x^3 - 2x^2y$

4x^3 = 2*2* x* x* x

2x^2y = 2*x*x*y

Greatest common factor is $2*x*x = 2x^2$

(2) the GCF for the polynomial $8x^4y + 6x^2y^2$

$8x^4y = 2*2*2*x*x*x*x*y$

$6x^2y^2 = 3*2*x*x*y*y$

GCF is $2*x*x*y=2x^2y$

(3) the GCF for the polynomial $12x^3y^2 - 20x^5y^3$

$12x^3y^2 = 2*2*3*x*x*x*y*y$

$20x^5y^3=5*2*2*x*x*x*x*x*y*y*y$

GCF is $2*2*x*x*x*y*y= 4x^3y^2$

(4) the GCF for the polynomial $-10x^3y^4 - 16x^5y^2$

$-10x^3y^4 =-2*5*x*x*x*y*y*y*y$

$-16x^5y^2=-2*2*2*2*x*x*x*x*x*y*y$

GCF is $-2*x*x*x*y*y= -2x^3y^2$

Evaluate the function f(x) = 2x2 - 6x + 3 for x = -1.

nadya68 [22]

Answer:

f(-1) = 11

Step-by-step explanation:

f(x) = 2x^2 - 6x + 3

Let x = -1

f(-1) = 2(-1)^2 -6(-1) +3

=2*1 +6 +3

=2+6+3

= 11

In set A, B wins 23 games.

In B, B wins 24 games.

In C, B wins 15 games.

In D, B wins 25 games.
