B.)191

C.)236

D.)128

Step-by-step explanation:

A) 12^2+(8-4)^3-15

144+(64)-15

208-15=193

B) (3*2)^3-5^2

6^3=216-5^2

216-25=191

I only showed work for A and B

Hope this helps !!

(x-1)(x-3)(x+5)(x+7)=297

mihalych1998 [28]

First simplify the expression into polynomial form,

$(x-1)(x-3)(x+5)(x+7)=297$

$x^4+8x^3-10x^2-104x+105=297$

$x^4+8x^3-10x^2-104x-192=0$

Now factor into,

$(x-4)(x+8)(x^2+4x+6)=0$

Which means the solutions are,

$x-4=0\implies\boxed{x_1=4}$

$x+8=0\implies\boxed{x_2=-8}$

and then two complex solutions because determinant of the third factor $D\lt0$ ,

$x^2+4x+6=0$

$x^2+4x+4=-2$

$(x+2)^2=-2\implies\boxed{x_3=i\sqrt{2}-2},\boxed{x_4=-i\sqrt{2}-2}$

Hope this helps :)

Which property does this represent -3x1=-3

katrin2010 [14]

The property used is: Multiplicative identity

Step-by-step explanation:

We need to identify the property in the equation : $-3\times 1=-3$

The property used is: Multiplicative identity

Multiplicative identity

The multiplicative identity property is defined as if you multiply a number by 1, the result of multiplication is that original number.

In the given expression $-3\times 1=-3$ -3 is multiplied by 1 to get -3 so, multiplicative identity.

write an equation in standard form for a line that is parallel to the line with an equation of y=3x-5 that passes through the po

lana66690 [7]

Answer:

The standard form of the equation is -3x + y = -19

Step-by-step explanation:

To find the standard form, we first need to note that the slope will be 3 since parallel lines have the same slope. Then we can use point-slope form and manipulate into standard form.

y - y1 = m(x - x1)

y - 5 = 3(x - 8)

y - 5 = 3x - 24

-3x + y - 5 = -24

-3x + y = -19
