Andrews [41]3 years ago
8 0

Answer:

We can have several equivalents.

It can be 1/784,  28^(-2),  or  1/ (28^2)

Step-by-step explanation:

4^(-2) * 7^(-2) =  (4*7)^(-2) = 28^(-2)

or  1 / (28^2)   is another equivalent.

4^(-2) * 7^(-2) = 28^(-2)

4^(-2) * 7^(-2) = = 1/784

What are the solutions to the equation?
Phantasy [73]

Answer:

x = -2 and 1

Step-by-step explanation:

Given :

f(x) = x+2

g(x) = -x²+4

The solution to the equation f(x) = g(x)

=> x+2 = -x²+4

=> x²+x = 4-2

=> x²+x -2 = 0

By factorisation

=> x²+2x-x -2 = 0

=> x(x+2) -1(x+2)

=> (x+2) (x-1)

x = -2 and 1
