Hey there!

If x = -3 then replace "x" with -3

New equation: -3^-2

(-1 × 3)^-2

(-1 / 3 )× 3

3 × 3 = 3^3 = 9 (Solving for your denominator)

(-1/3)^2

= (1/9)

This your answer is: 1/9

Good luck on your assignment and enjoy your day!

a rhombus as an area of 72 ft and the product of the diagonals is 144. What is the length of each diagonal?
SashulF [63]

A = (1/2)(x)(y)

Let x = diagonal 1

Let y = diagonal 2

The product of xy = 144.

This means that x = 12 and y = 12.

So, 12 • 12 = 144

Each diagonal is 12 feet.

Prove:

72 feet = (1/2)(12)(12) feet

72 feet = (1/2)(144) feet

72 feet = 72 feet
