Answer:

let x=one number =

x-2= another number

x²- (x-2)²=20

x²-x²-4x+4=20

-4x=20-4

-4x=16

x=16/-4

x=-4

one number is -4

x-2

-4-2

=-6

the another number is -6

If f(x) and f⁻¹(x) are inverse functions of each other and f(x)=2x+5, what is f⁻¹(8)?
dexar [7]

Answer:

3/2.

Step-by-step explanation:

f(x)=2x+5   Finding the inverse:

y = 2x + 5

2x = y - 5

x = (y - 5)/2

So the inverse f-1(x) = (x - 5)/2

and f-1(8) = (8-5)/2

= 3/2.

The perimeter of a isclose triangle is 24in and the length of the side is 4 in find the 2 other sides
Scrat [10]

Answer:

10 inches

Step-by-step explanation:

Given

Shape: Isosceles Triangle

Perimeter=24\ in

Side = 4\ in

Required

Find the length of the other two sides

Represent the other sides with x.

Since it is an isosceles triangle, 2 sides are equal.

So, we have:

x + x + 4 = 24

2x + 4 = 24

Collect Like Terms

2x = 24-4

2x = 20

Divide both sides by 2

\frac{2x}{2} = \frac{20}{2}

x = \frac{20}{2}

x = 10

<em>The other sides are 10in each</em>
