What are the solutions to the equation x² = 169?

select each correct answer.

−84.5

−13

13

84.5

the solutions are 13 and -13

Step-by-step explanation:

13 x 13= 169

-13 x -13=169

a negative times a negative equals a positive

answer: it is a.,b.,d.

step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
