The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100.

Mice21 [21]

Answer:

$1. x^2-10$ because the area expression can be rewritten as $(x^2-10)(x^2+10)$ which equals $(x^2-10)((x^2-10)+20).$

Step-by-step explanation:

Area of the rectangle $=(x^4-100)$

$x^4-100=(x^2)^2-10^2\\$Applying difference of two squares: a^2-b^2=(a-b)(a+b)\\(x^2)^2-10^2=(x^2-10)(x^2+10)$

Since the length of a rectangle is 20 units more than its width.

$Width: x^2-10\\Length=x^2+10=x^2-10+20$

The correct option is therefore 1.

Would -x - 3y = -1 convert into y = -1/3 x - 1/3

vfiekz [6]

Answer:

Yes, -x - 3y = -1 is the same as y = -1/3x - 1/3

Step-by-step explanation:

-x - 3y = -1

Add x to both sides which gives you

-3y = x-1

Divide both sides by -3 which gives you

y = -1/3x-1/3

Reminder whatever you do to one side you have to do to the other side!

Hope this helps!
