Answer:

x=4

Step-by-step explanation:

(4-1)(4-3)(4+5)(4+7)=297

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 :)

Step-by-step explanation:

1) Your problem → (4x^2 - 17x^3 + 9) - (x^2 + 9x + 23x^2 + 11)

(-17x^3+4x^2+9)-(x^2+23x^2+9x+11)

=-17x^3+4x^2+9-x^2-23x^2-9x-11

=-17x^3+4x^2-x^2-23x^2-9x+9-11

=-17x^3-20x^2-9x-2

2) Your problem → 0 - 19.73 - 25x^2 - 12x - 3

=0-19.73-25x2-12x-3

=-25x^2-12x-22.73

3) - 10.x^3 – 162x^2 – 24x - 4

4) Your problem → 17x^3 - 20x^2 - 9x^2

=17x^3-20x^2-9x^2

=17x^3-29x^2

5) -16x^3 – 243x^2 – 12x – 3

draw and label a parallelogram with a base twice as long as the height and an area less than 60 square inches. find the area
liubo4ka [24]
Answer: 5 cm by 10 cm gives an area of 50 cm^2

To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.

To find the area, multiply the base times height.

This will give you: 5 x 10 = 50 which is less than 60.

A model car is 8 inches long and 5.2
Sphinxa [80]
Use proportions here - 8/5.2 = 96/width of actual car. using cross multiplication, 5.2*96 = 8x. this gives you 499.2 = 8x. divide both sides by eight to get x=62.4. the width of the actual car is 62.4 inches.
