Please help!! I need to make up my own formula with LENGTH X WIDTH, can someone please help me!!!
damaskus [11]

Answer:

A = s²

Step-by-step explanation:

A = s² where s represents the side lengths

Since the side lengths of a square are always the same, you can use the formula A = s² for a square instead of using A=l(w)

X^(2)-4x-17=0<br> Please show work step by step
Dimas [21]

Step-by-step explanation:

It seems here that they are asking us to solve for x

to do this we first need to factor

Since we can't factor this using the normal method we can instead do this

x^2 -4x-17=0

add 4 to both sides as it is a perfect square

x^2 - 4x + 4  = 17 +4

(x-2)^2 = sqrt 21

x-2 = ±  4.58

x -2 = 4.58    x-2 = -4.58

x= 6.58          x=-2.58

Or just say x=2+√21 or x=2−√21
