you must factorize it as a difference of squares

a^2-b^2 = (a-b)(a+b),

9b^2-25 = (3b)^{2-(5)^2= (3b-5)(3b+5)

Find the value of x. Hint: the chords are congruent/equal (I will give 20 points)

Advocard [28]

$\huge \purple{\tt{Answer:}}$

If the chords are equal , then the measurement of both the chords will also be the same . That means ,

$\sf {6x-7 =35} \\\\\ \implies \sf {6x = 35 +7} \\\\\ \implies \sf {6x=42} \\\\\ \implies \sf{x= {\dfrac{\bcancel {42}^7}{\bcancel{6}}}} \\\\\ \implies \sf{x=7}$

Update for the first one

PSYCHO15rus [73]

Answer:

y = x + 2.5

Step-by-step explanation:

slope = (y2-y1)/(x2-x1) where the variables indicate the coordinates of the two points

slope = (2.5-1.5)/(0+1) = 1

equation = y-y1 = m(x-x1)

y - 2.5 = x

y = x + 2.5
